This C program takes a input from user and reverses that sentence using recursion.
#include <stdio.h>
void reverse();
void main()
{
printf("Please enter a sentence: ");
reverse();
}
void reverse()
{
char c;
scanf("%c", &c);
if (c != '\n') {
reverse();
printf("%c", c);
}
}
This program prints "Please enter a sentence: " in screen and
then takes input from the user.
reverse() function called and function stores the first letter
entered by user and stores in variable c. If that variable is other
than '\n' [enter character] then, again reverse() function is
called. Then, the second character is stored in variable c of
second reverse function. This process goes on until the user enters
'\n'.
When, user enters '\n', the last function reverse() function returns to second last reverse() function and prints the last character. Second last reverse() function returns to the third last reverse() function and prints second last character. This process goes on and the final output will be the reversed sentence.
