Alternatives for str.substr using <cstring> library?

Question

Hi I was wondering if there is an alternative of str.substring() in string.h. If not, what is an efficient alternative?

Answer 1

Assuming that we all agree that using c++ it is safer and more professional to use the standard library tools.

That said, if we're talking about C and not C++, this should be one of the ways to extract a substring with the "string.h" library:

#include <stdio.h>
#include <string.h>

int main() {
    char test[] = "abcdef";
    char subtext[3];
    
    memcpy(subtext, &test[1], 2); //Result: "bc"
    subtext[2] = '\0';
    
    printf("%s", subtext);
    
    return 0;
}
