Write program in C that would read 3 figures from the 1 up to the 999 and him it presents all in a line from smallest in biggest.

As , and suggested, it helps to see a working example. Below is a compact, robust C program that reads three integers (each must be 1..999), validates the input, and prints them on one line from smallest to largest. It uses only simple comparisons and swaps — minimal and easy to understand for three values.

#include <stdio.h>

int main(void) {
    int a, b, c, tmp;
    printf("Enter three integers (1-999): ");
    if (scanf("%d %d %d", &a, &b, &c) != 3) {
        fprintf(stderr, "Invalid input: expected three integers\n");
        return 1;
    }
    if (a < 1 || a > 999 || b < 1 || b > 999 || c < 1 || c > 999) {
        fprintf(stderr, "Each number must be between 1 and 999\n");
        return 1;
    }
    if (a > b) { tmp = a; a = b; b = tmp; }
    if (a > c) { tmp = a; a = c; c = tmp; }
    if (b > c) { tmp = b; b = c; c = tmp; }
    printf("%d %d %d\n", a, b, c);
    return 0;
}

Notes: the three pairwise swaps guarantee a <= b <= c after execution. Check scanf's return value to catch non-numeric input; validate ranges explicitly since the problem requires 1..999. If a more general solution is wanted (n numbers), use an array plus qsort or a simple sort routine. If this program doesn't behave as expected for specific inputs, post the exact input and compiler errors — that will make troubleshooting easier, as and recommended.

You must post your code and ask for solving. ;)

Me and VatooVatoo posted the message simultaneously. I would've deleted my post, but since that isn't an option i just left it.
