Question

C language: Write a program that uses a function to check if a user entered string is a palindrome. Based on the return value of the function, the results are printed in the main() function. (do not print results in function to check for palindrome)

A palindrome reads the same forward as backward for example tacocat or civic.

int isPalindrome(char a[])
{
int length,i;
int flag=0;
length =strlen(a);

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

return flag;
}

int main(){
char a[100];

printf("Enter a string: ");
scanf("%s",&a);

if (isPalindrome(a)) {
printf("%s is not a palindrome\n",a);
}
else {
printf("%s is a palindrome\n",a);
}

return 0;
}

nter a string: tacocat tacocat is a palindrome rocess returned 0 〈0x0〉 execution time : 3.708 s ress any key to continue.

nter a string: cicic cicic is a palindrome rocess returned 0 <0x0) execution time : 2.487 s Press any key to continue
