How floats are stored in C compiler?
In C programming language, float is a short term for floating point.Floating point numbers are generally represented in the form of Institute of Electrical and Electronics Engineers (IEEE) format.The IEEE format uses a sign bit, a mantissa and an exponent for representing the power of 2.The sign bit denotes the sign of the number: a 0 represents a positive value and a 1 denotes a negative value.The mantissa represented in binary after converting into its normalized form. After normalization mantissa, the most significant digit is always 1.The exponent is an integer stored in unsigned binary format after adding a positive ...
Read MoreHow to print the range of numbers using C language?
ProblemFor given number try to find the range in which that number exists.SolutionHere, we are learning how to find the ranges of a number.The logic that we apply to find range is −lower= (n/10) * 10; /*the arithmetic operators work from left to right*/ upper = lower+10;ExplanationLet number n=45Lower=(42/10)*10 // division returns quotient =4*10 =40Upper=40+10=50Range − lower-upper − 40-50ExampleFollowing is the C program for printing the range of numbers −#include main(){ int n, lower, upper; printf("Enter a number:"); scanf("%d", &n); lower= (n/10) * 10; /*the arithmetic operators work from left to right*/ upper ...
Read MoreHow to pass the individual members as arguments to function using structure elements?
There are three ways by which the values of structure can be transferred from one function to another. They are as follows −Passing individual members as arguments to function.Passing entire structure as an argument to function.Passing the address of structure as an argument to function.Now let’s see how to pass an individual member of structure elements as arguments to function.Each member is passed as an argument in the function call.They are collected independently in ordinary variables in function header.ExampleGiven below is a C program to demonstrate passing individual arguments of structure to a function − Live Demo#include struct date{ int ...
Read MoreWhat are the different computer languages?
The programming languages are used to give instructions to the computer in a language which a computer can understand.Computer languages are classified into three types as follows −Machine languagesSymbolic languagesHigh level languagesMachine languagesComputer is a machine. Since, its memory can store only 1’s and 0’s, instructions must be given to the computer in streams of 1’s and 0’s i.e. binary code.These are easily understandable by the machine.Programs written in binary code can be directly entered into computer for execution and it is known as machine language.Advantages of machine language include −Execution is very fast.It is very difficult to write and ...
Read MoreExplain the Format of C language
C programming is a general-purpose, procedural, imperative computer programming language. In C language, we see thatStatements are terminated with semicolons.C is case sensitiveIndentation is ignored by the compiler.Strings are placed in double quotes.Library functions are lowercase.Newlines are handled via Format of CThe format of C programming language is explained below −SemicolonsSemicolons are very important in C.It tells the compiler, where one statement ends and the next statement begins.If we fail to place the semicolon after each statement, you will get compilation errors.Case SensitivityC is a case sensitive language. Although, int compiles, "Int”, "INT” or any other variation will not be ...
Read MoreCheck if the value entered is palindrome or not using C language
A palindrome is nothing but any word, number, sentence, or other sequence of characters that reads the same backward as forward.In this programming, we are trying to enter a number from console, and assign that number to temp variable.If number is greater than zero, apply the logic given below −while(n>0){ r=n%10; sum=(sum*10)+r; n=n/10; }If temp=sum, then the given number is a palindrome. Otherwise, it is not a palindrome.ExampleFollowing is the C program for verification of a value being palindrome −#include #include void main(){ int n, r, sum=0, temp; printf("Enter a number: "); scanf("%d", &n); ...
Read MoreWhat happens if we include header file for two times in a C program?
C header files include some predefined functions. For example, printf() and scanf() functions are defined in the stdio.h header file.Each header files in C contains different predefined functions to make programs simple to understand.When a header file is included two times in a C program, the second one gets ignored. In actual, the #, called the include, preceding a header file ensures that it is included only once during the compilation process.Example 1Following is the C program for computing an average of three numbers − Live Demo#include #include //header file included twice ,ignored by compiler main(){ int a, b, c, ...
Read MoreWhat are the different searching techniques in C language?
Searching technique refers to finding a key element among the list of elements.If the given element is present in the list, then the searching process is said to be successful.If the given element is not present in the list, then the searching process is said to be unsuccessful.C language provides two types of searching techniques. They are as follows −Linear searchBinary searchLinear SearchSearching for the key element is done in a linear fashion.It is the simplest searching technique.It does not expect the list to be sorted.Limitation − It consumes more time and reduce the power of system.Input (i/p)Unsorted list of ...
Read MoreExplain the Random accessing files in C language
Random accessing of files in C language can be done with the help of the following functions −ftell ( )rewind ( )fseek ( )ftell ( )It returns the current position of the file ptr.The syntax is as follows −int n = ftell (file pointer)For example, FILE *fp; int n; _____ _____ _____ n = ftell (fp);Note − ftell ( ) is used for counting the number of characters which are entered into a file.rewind ( )It makes file ptr move to beginning of the file.The syntax is as follows −rewind (file pointer);For example, FILE *fp; ----- ----- ...
Read MoreC Program for copying the contents of one file into another file
File is a collection of records (or) is a place on hard disk, where data is stored permanently. By using C commands, we can access the files in different ways.Operations on filesThe operations that can be carried out on files in C language are as follows −Naming the file.Opening the file.Reading from the file.Writing into the file.Closing the file.SyntaxThe syntax for opening and naming file is as follows −FILE *File pointer;For example, FILE * fptr;File pointer = fopen ("File name”, "mode”);For example, fptr = fopen ("sample.txt”, "r”);FILE *fp; fp = fopen ("sample.txt”, "w”);The syntax for reading from file is as ...
