How to add two complex numbers by passing structure to a function in C language?
In order to add two complex numbers in C programming language, the user has to take two complex numbers as structure members and perform addition operation on those two numbers by creating a user-defined function.AlgorithmRefer an algorithm given below for addition of two complex numbers.Step 1: Declare struct complex with data members. Step 2: Declare name for structure and variables. Step 3: Enter real and imaginary part for first complex number at run time. Step 4: Enter real and imaginary part for second complex number at runtime Step 5: Compute addition of number1 and number2 by calling function. Go to ...
Read MoreExplain the concept of an array within a structure in C programming
An array of structure in C programming is a collection of different datatype variables, grouped together under a single name.General form of structure declarationThe structural declaration is as follows −struct tagname{ datatype member1; datatype member2; datatype member n; };Here, struct is the keyword.tagname specifies the name of structure.member1, member2 specifies the data items that make up structure.ExampleThe following example shows the usage of array within a structure in C programming −struct book{ int pages; char author [30]; float price; };ExampleFollowing is the C program to demonstrate the use of an array within a structure ...

An array of characters is called a string.DeclarationThe syntax for declaring an array is as follows −char stringname [size];For example − char string[50]; string of length 50 charactersInitializationUsing single character constant −char string[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constants −char string[10] = "Hello":;Accessing − There is a control string "%s" used for accessing the string till it encounters ‘\0’.Now, let us understand what are the arrays of pointers in C programming language.Arrays of pointers: (to strings)It is an array whose elements are ptrs to the base add of the string.It is declared and initialized as follows ...

An array of characters is called a string.DeclarationThe syntax for declaring an array is as follows −char stringname [size];For example − char string[50]; string of length 50 charactersInitializationUsing single character constant −char string[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constants −char string[10] = "Hello":;Accessing − There is a control string "%s" used for accessing the string till it encounters ‘\0’.The strrev( ) FunctionThis function is used for reversing a string.The reversed string is stored in the same string.SyntaxThe syntax for strrev() function is as follows −strrev (string)ExampleThe following program shows the usage of strrev() function.#include main ( ...
Read MoreWhat is strncmp() Function in C language?
The C library function int strncmp(const char *str1, const char *str2, size_t n) compares at most the first n bytes of str1 and str2.An array of characters is called a string.DeclarationThe syntax for declaring an array is as follows −char stringname [size];For example − char string[50]; string of length 50 charactersInitializationUsing single character constant −char string[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constants −char string[10] = "Hello":;Accessing − There is a control string "%s" used for accessing the string till it encounters ‘\0’.The strncmp ( ) FunctionThis function is used for comparing first ‘n’ characters of 2 ...
Read MoreWhat is strncat() Function in C language?
The C library function char *strncat(char *dest, const char *src, size_t n) appends the string pointed to by src to the end of the string pointed to by dest up to n characters long.An array of characters is called a string.DeclarationFollowing is the declaration for an array −char stringname [size];For example: char string[50]; string of length 50 charactersInitializationUsing single character constant −char string[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constants −char string[10] = "Hello":;Accessing − There is a control string "%s" used for accessing the string till it encounters ‘\0’.The strncat( ) functionThis is used for combining ...
Read MoreWhat is pass by value in C language?
Pass by value is termed as the values which are sent as arguments in C programming language.AlgorithmAn algorithm is given below to explain the working of pass by value in C language.START Step 1: Declare a function that to be called. Step 2: Declare variables. Step 3: Enter two variables a, b at runtime. Step 4: calling function jump to step 6. Step 5: Print the result values a, b. Step 6: Called function swap. i. Declare temp variable ii. Temp=a iii. a=b iv. b=temp STOPExampleGiven below is the C program to swap the two numbers ...
Read MoreExplain scope rules related to the functions in C language
Scope rules are related to the following factors −Accessibility of a variables.Period of existence of a variable.Boundary of usage of variables.Scope rules related to functions are as followsFunction which is a self-contained block that performs a particular task.Variables that are declared within the function body are called local variables.These variables only exist inside the specific function that creates them. They are unknown to other functions and to the main functions too.The existence of local variables ends when the function completes its specific task and returns to the calling point.Example 1Following is the C program for scope rules related to functions ...

An array is a group of related items that store with a common name.SyntaxThe syntax is as follows for declaring an array −datatype array_name [size];Types of arraysArrays are broadly classified into three types. They are as follows −One – dimensional arraysTwo – dimensional arraysMulti – dimensional arraysInitializationAn array can be initialized in two ways, which are as follows −Compile time initialization.Runtime initialization.Two multidimensional arraysThese are used in situations where a table of values have to be stored (or) in matrices applications.SyntaxThe syntax is given below −datatype array_ name [rowsize] [column size];For example int a[5] [5];a[0][0]10a[0][1]20a[0][2]30a[1][0]40a[1][1]50a[1][2]60a[2][0]a[2][1]a[2][2]Following is the C Program for ...
Read MoreWhat are the predefined functions in C language?
Functions are broadly classified into two types, which are as follows −Predefined functionsUser defined functionsPredefined (or) library functionsThese functions are already defined in the system libraries.Programmer will reuse the already present code in the system libraries to write error free code.But to use the library functions, user must be aware of syntax of the function.Example −sqrt() function is available in math.h library and its usage is −y= sqrt (x) x number must be positive eg: y = sqrt (25) then ‘y’ = 5printf ( ) present in stdio.h library.clrscr ( ) present in conio.h library.ExampleGiven below is the C program ...
