What are string function in C? Write a program to print the given text in reverse order.
String function in C
C program allows multiple library or built-in function for string manipulation which are defined under #include<string.h>. some string function are
strlen():- This function takes a string as a parameter and return the integer value as the length of string contain all the character.
Syntax of strlen()
int variable=strlen(string);
strcpy():- The function strcpy() is use to copy one string to another string. It takes two string as a parameter and copy characters of source string to destination string.
Syntax of strcpy()
strcpy(destination string, source string);
strcat():- This function is used to concatenate i.e. it appends a string to the end of next string. This function takes two string as a parameter and copy character by character of the second string to the end of first string.
syntax of strcat()
strcat(string1,string2);
strrev():- strrev() function is use to reverse all the character. It takes one string as a parameter and reverse all the character of a string except null character.
Syntax of strrev()
strrev(string);
strupr():- This function strupr() takes a string as a parameter and convert all alphabets of a string into capital letters.
Syntax of strupr()
strupr(string);
strlwr():- This function strlwr() takes a string as a parameter and convert all alphabets of a string into small letters.
Syntax of strlwr()
strlwr (string);
strcmp():- This function takes two string as a parameter and compares to each other. It returns an integer where the value is
(i) >0 -------- if first string is greater than second string
(ii) <0---------If first sting is less than second string
(iii) =0---------if both string are equal
Syntax of strcmp()
int variable = strcmp(string1, string2);
Write a program to print the given text in reverse order.
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
char string1[20];
printf("\n Enter a string");
scanf("%s",string1);
strrev(string1);
printf("\n Reverse string=%s", string1);
getch();
}
