C Program to Reverse a Sentence Using Recursion

* This program first prints Enter a sentence: . Then, the reverseSentence() function is called.

* This function stores the first letter entered by the user in c. If the variable is any character other than \n (newline), reverseSentence() is called again.

* This process goes on until the user hits enter.

* When the user hits enter, the reverseSentence() function starts printing characters from last.

Program :

#include <stdio.h>
void reverseSentence();
int main() {
    printf("Enter a sentence: ");
    reverseSentence();
    return 0;
}

void reverseSentence() {
    char c;
    scanf("%c", &c);
    if (c != '\n') {
        reverseSentence();
        printf("%c", c);
    }
}
