    conditions array, string

    I want to number (compute 10) into char for example [1] and conditions if it smaller return 1 else return 1. If you know what i mean? I select lenght char [1] and when i compute string 100+100=200 i want with conditions if else 0 for larger then char [1] and 1 for smaller. Thank you



    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    
    int main(void)
    {
        char src[] = "10 10";
        char *data = src;
        int pocet;
        int v;
        int compute = 0;
    
        while (sscanf(data, " %d%n", &v, &pocet) == 1)
        {
            compute += v;
            data += pocet;
            printf("cislo: %5d; compute = %5d; pocet = %5d\n", v, compute, pocet);
        }
    
        printf("compute = %d\n", compute);
    {
        char str[5]= {compute,'\0' };
        printf("compute = %ld\n", str);
    
        if (str > 10)
        printf("0 \n");
    else
        printf("1 \n");
    }
        return 0;
    }

    Well,
    Code:
    char str[5];
    sprintf(str,"%d",compute);
    Saying strlen(str) > 2 is just the long way of saying compute >= 100.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
