Problem in C

Write a function is_palindrome() embedded in a program, that takes a pointer to the beginning of a string and returns a boolean value. That value is true if the string is a palindrome, false otherwise. The program is supposed to get a string from the user and pass it to the function.

You can use gets() to accomplish this, or, alternatively and more secure, fgets(). A call to fgets() would look something like that:

fgets(string, 80, stdin);

Be aware though that this function includes the newline character at the end of the string, which you will want to remove.

Hand in the C program file, commented *abundantly*.

Explanation / Answer

#include <stdio.h>

int is_palindrome(char *s) {
int n=0;
int i;
for(i=0; s[i]!=''; i++){
n++;
}
for(i=0; i<n; i++){
if(s[i] != s[n-1-i]){
return 0;
}
}
return 1;
}
int main()
{
char string[80];
int result;
printf("Enter the string: ");
fgets(string, 80, stdin);
result = is_palindrome(string);
if( result ==1){
printf("Given string is a palidrome ");
}
else{
printf("Given string is not a palidrome ");
}
return 0;
}

Output:

Enter the string: Suresh

Given string is not a palidrome

Enter the string: madam

Given string is a palidrome
