1. Statements with conditional statements

This page has some examples and questions involving assignment statements with conditional statements.

2. Example 1

Here is the C code.

#include <stdio.h>

int main() {
	int m, c, p, t, z;
	m = 6;
	c = 4;
	p = c * 5;
	t = 3 / p;
	z = m + t;
	if (p >= t) {
		z += 2;
		}
	else {
		z++;
		}
	printf("%d",z % 10);
	return 0;
	}

Here are the final values of the variables in the program (main).

m == 6 c == 4 p == 20 t == 0 z == 8

The final value of variable z is 8. The output is the remainder left over when z is divided by 10, which is 8 (the answer). Here is the output of the C code.

8

3. Example 2

Here is the C code.

#include <stdio.h>

int main() {
	int d, k, h, e, f;
	d = 4;
	k = 3;
	h = 7 / k;
	e = h * 5;
	f = d + e;
	if (h <= e) {
		f++;
		}
	else {
		f += 2;
		}
	printf("%d",f % 10);
	return 0;
	}

Here are the final values of the variables in the program (main).

d == 4 k == 3 h == 2 e == 10 f == 15

The final value of variable f is 15. The output is the remainder left over when f is divided by 10, which is 5 (the answer). Here is the output of the C code.

5

4. Example 3

Here is the C code.

#include <stdio.h>

int main() {
	int m, x, r, n, d;
	m = 4;
	x = 6;
	r = m + 7;
	n = x * 3;
	d = r / n;
	if (r > n) {
		d += 2;
		}
	else {
		d++;
		}
	printf("%d",d % 10);
	return 0;
	}

Here are the final values of the variables in the program (main).

m == 4 x == 6 r == 11 n == 18 d == 1

The final value of variable d is 1. The output is the remainder left over when d is divided by 10, which is 1 (the answer). Here is the output of the C code.
