Answer 2

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

void ToReadableWeeksDays(int totalDays, char *out, size_t outSize) {
    int weeks = totalDays / 7;   // whole weeks
    int days  = totalDays % 7;   // leftover days

    // Build the string manually
    snprintf(out, outSize,
             "%d week%s and %d day%s",
             weeks,
             (weeks == 1 ? "" : "s"),
             days,
             (days == 1 ? "" : "s"));
}

int main(void) {
    int days = 26;
    char buffer[64];

    ToReadableWeeksDays(days, buffer, sizeof(buffer));

    printf("%s\n", buffer);

    return 0;
}
