array -> inverse array manually without library and check if it palindrome

Question

When studying arrays I got a problem.
I'd appreciate if you help me to get output for this code.
I need to

• inverse array in new array
• compare both arrays to check whether input is a palindrome or not
• without using string.h library

# include<stdio.h>
int main(void)
{
    char pal[15],palcpy[15];
    int slen,i,j;
    printf("\t\tpalindrome checker :)\n\nplease input the word you need to check : ");
    scanf("%s", pal);
    slen = strlen(pal);
    
    
    for(i=slen ; i>=0 ; i--)
    {
        for(j=0 ; j<=slen ; j++)
        {
            palcpy[j] = pal[i];
        }
    }
    printf("%s", pal);

return 0;
}
    

Answer 1

In line with https://ericlippert.com/2014/03/21/find-a-simpler-problem/ ( and How do I ask and answer homework questions? ) I recommend:

• Start with a HelloWorld, test
• Extend to read a string and echo, test
• Extend to copy the string to a second array, test
• Modify to echo from copy, test
• Extend to verify that original and copy are identical, test
• Modify to copy in reverse, test
