1. Statements with variables

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

2. Example 1

Here is the C code.

#include <stdio.h>

int main() {
	int d, h, z, b, c;
	d = 4;
	h = 3;
	z = 5 / h;
	b = d * z;
	c = 6 + b;
	printf("%d",c % 10);
	return 0;
	}

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

d == 4 h == 3 z == 1 b == 4 c == 10

The final value of variable c is 10. The output is the remainder left over when c is divided by 10, which is 0 (the answer). Here is the output of the C code.

0

3. Example 2

Here is the C code.

#include <stdio.h>

int main() {
	int d, p, z, m, b;
	d = 5;
	p = 4;
	z = d * 3;
	m = z / p;
	b = 7 + m;
	printf("%d",b % 10);
	return 0;
	}

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

d == 5 p == 4 z == 15 m == 3 b == 10

The final value of variable b is 10. The output is the remainder left over when b is divided by 10, which is 0 (the answer). Here is the output of the C code.

0

4. Example 3

Here is the C code.

#include <stdio.h>

int main() {
	int e, w, a, h, y;
	e = 4;
	w = 3;
	a = 5 + e;
	h = 7 / w;
	y = a * h;
	printf("%d",y % 10);
	return 0;
	}

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

e == 4 w == 3 a == 9 h == 2 y == 18

The final value of variable y is 18. The output is the remainder left over when y is divided by 10, which is 8 (the answer). Here is the output of the C code.
