In this article we will learn to implement a C program to reverse a given string. A C program is provided below to reverse a given string without using predefined function.
Program is as follows:
#include<stdio.h>
#include<string.h>
int main()
{
char str[20];
printf("Enter a string: ");
scanf("%s", str);
int length = strlen(str);
for(int i=0, j=length-1; i<j; i++, j--)
{
int temp = str[i];
str[i] = str[j];
str[j] = temp;
}
printf("Reversed string is: %s", str);
return 0;
}
Input and output for the above program is as follows:
Enter a string: india
Reversed string is: aidni
