String is longer than expected in C

Question

Here\'s my code

#include 
#include 

int main(){
    char pal[8] = \"ciaooaic\";
    char pal1[7] = \"ciaoaic\";
    int lenPa         


        

Answer 1

1. You don't leave room for a null terminator, as you pass them to strlen(), therefore your code exhibits undefined behaviour -

char pal[8] = "ciaooaic";
char pal1[7] = "ciaoaic";

Leave a space for '\0'. Declare and initialize like this -

char pal[9] = "ciaooaic";
char pal1[8] = "ciaoaic";

2. And strlen() returns size_t not int , so write like this -

size_t lenPal = strlen(pal);
size_t lenPal1 = strlen(pal1);

and use %zu specifier to print both these variables.
