What are executable statements in C language?
A ‘C’ program contains executable statements. A compiler helps to translate the executable statements into machine language.When a user runs the program, he/she machines the language statements which are executed by the compiler.Types of executable statementsThe types of executable statements in C language are as follows −Input – output statementsAssignment statementsInput-output statementsStoring a value into memory is called ‘input operation’.After executing the computations, the results are stored in memory and the results can be displayed to the user by ‘output operation’.All i/o operations are performed using input / output functions.The most common I/O functions are supplied through the preprocessor directive ...
Read MoreExplain different types of expressions in C program
An expression is a combination of operators and operands which reduces to a single value. An operation is performed on a data item which is called an operand. An operator indicates an operation to be performed on data.For example, z = 3+2*1z = 5Primary expressions − It is an operand which can be a name, a constant or any parenthesized expression. Example − c = a+ (5*b);Postfix expressions − In a postfix expression, the operator will be after the operand. Example − ab+Prefix expressions − n a prefix expression, the operator is before the operand. Example − +abUnary expression − ...
Read MoreExplain the pointers for inter-function communication in C language.
We know that functions can be called by value and called by reference.If the actual parameter should not change in called function, pass the parameter-by value.If the value of actual parameter should get changed in called function, then use pass-by reference.If the function has to return more than one value, return these values indirectly by using call-by-reference. Read Also: Function Call by Value in C and Function Call by Reference in C ExampleFollowing is the C program for the demonstration of returning the multiple values −#include void main() { void areaperi(int, int*, int*); int r; float a, ...
Read MoreC program to find the unique elements in an array.
ProblemFind the non-repeating element in an array by using the two loops. One is for the current element and the other is to check, if an element is already present in an array or not.SolutionConsider an example given below −15, 15, 16, 15, 13, 15Here, the non-repeated elements in an array are 16 and 13.AlgorithmRefer an algorithm given below for finding the unique or the non-repeated elements in an array.Step 1 − Declare an array and input the array elements at run time.Step 2 − Start traversing the array and check, if the current element is already present in an ...
Read MoreC program to sort names in alphabetical order using structures
Structure is a collection of different datatype variables, grouped together under a single name.Features of structureThe features of structure in the C programming language are as follows −It is possible to copy the contents of all the structure elements of different datatypes to another structure variable of its type by using an assignment operator.For handling the complex datatypes, it is better to create structure within another structure, which is called nested structures.It is possible to pass an entire structure, individual elements of structure and an address of structure to a function.It is possible to create structure pointers.Declaration and initialization of ...
Read MoreC Program to delete the duplicate elements in an array
Try to delete the same numbers present in an array. The resultant array consists of unique elements.The logic to delete the duplicate elements in an array is as follows −for(i=0;i
Read MoreC program to print multiplication table by using for Loop
A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.AlgorithmGiven below is an algorithm to print multiplication table by using for loop in C language −Step 1: Enter a number to print table at runtime. Step 2: Read that number from keyboard. Step 3: Using for loop print number*I 10 times. // for(i=1; i
Read MoreHow to write a simple calculator program using C language?
A calculator is a simple tool that helps us to calculate mathematical operations easily and quickly. A basic calculator can perform simple arithmetic operations like subtraction, addition, multiplication, and division. Begin by writing the C code to create a simple calculator. Then, follow the algorithm given below to write a C program. Algorithm Step 1: Declare variables Step 2: Enter any operator at runtime Step 3: Enter any two integer values at runtime Step 4: Apply switch case to select the operator: // case '+': result = num1 + num2; ...
Read MoreExplain the quick sort technique in C language.
Sorting is the process of arranging the elements either in ascending (or) descending order. This process is determined for accessing and organizing data quickly. Sorting helps in optimizing search techniques and operations that make the data more readable and accessible. This involves comparing elements that rearrange the readable and accessible determined by criteria. Types of sorting Sorting in C involves different methods that determine the data in a certain order. C language provides five sorting techniques, which are as follows − Bubble sort (or) Exchange Sort Selection sort ...
Read MoreWhat do you mean by odd loops in C language?
In C programming language, control statements are used to repeat a set of statements, while conditional statements are used for decision-making. These decision-making statements are also used to determine one or more conditions that decides whether a set of statements should be executed. They are as follows − for loop while loop do-while loop For loop and while loop, the condition specifies the number of times the loop can be executed. The "for loop" The for loop is an entry-controlled loop that executes statements until the ...
