Thread: case sensitive and spacing

Code:

#include <stdio.h>
#include <string.h>
int main(){
char string1[20];
int i, length;
int flag = 0;
printf("Enter a string: ");
scanf("%s", string1);
length = strlen(string1);

for(i=0;i < length ;i++){
if(string1[i] != string1[length-i-1]){
flag = 1;
break; } }

if (flag) {
printf("%s is not a palindrome ", string1); }
else {
printf("%s is a palindrome ", string1); }

return 0;
 }

Hey guys, I have a program that takes a string and says if it is a palindrome or not. Right now it is case sensitive (Pop would not count as a palindrome) and it also disregards spacing (p o p is a palindrome). How do I change it so that Pop WOULD count as a palindrome and p o p WOULD NOT count as one? Pretty much what do I need to do to make it case insensitive and also make it so that if there are spaces, it does not count as a palindrome? Thanks for any help.

can those be used with C as well?

Yes, just remove the c from the library name and add .h

So, include <ctype.h> -- not <cctype>
