#include int main() { char a[100], b[100]; printf("Enter the string to check if it is a palindrome\n"); gets(a); strcpy(b,a); strrev(b); if( strcmp(a,b) == 0 ) printf("Entered string is a palindrome.\n"); else printf("Entered string is not a palindrome.\n"); return 0; } Consider a palindrome string: lol, -----index: 0 1 2 . printf("%c",mystring[i]); Logic to check palindrome string in C program. A string which remains the same on reversal is a palindrome. For example, "madam" is a palindrome string whereas apple is not a palindrome string. In this program, we use the fact that, If a string is palindrome then leftmost character of the string is equal to the rightmost character of the string. Find code solutions to questions for lab practicals and assignments. Reverse it (we recommend not to use strrev function as it's not compatible with C99).
