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

int main(void)
{
    char string[] = "c c++ java python php javascript c#";
    char delimiters[] = " ";

    char* p = strtok(string, delimiters);

    while (p) {
        printf("%s = %zu\n", p, strlen(p));
        p = strtok(NULL, delimiters);
    }

    return 0;

Answer 2

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

int main(void)
{
    char s[] = "c c++ java python javascript c# php";
    
    int size = strlen(s);
    int endIndex, startIndex = 0;

    for (int i = 0; i < size; i++) {
        if (s[i] == ' ' || i == size - 1) {
            endIndex = i;
            if (i == size - 1) endIndex = size;
            printf("%.*s = %d\n", (endIndex - startIndex), s + startIndex, (endIndex - startIndex));
            startIndex = i + 1;
        }
    }

    return 0;
}
