Compiler: Visual C++ Express Edition 2005

Compiled on Platform: Windows XP Pro SP2

Header file: Standard

Additional library: none/default

Additional project setting: Set project to be compiled as C

Project -> your_project_name Properties -> Configuration Properties -> C/C++ -> Advanced -> Compiled As: Compiled as C Code (/TC)

To do: To do the basic mathematics operations which demonstrate the C operators, operands and the operations

To show: How to use C operators, operands and basic mathematics operations

 

/* Simple mathematics calculation */

#include <stdio.h>

 

/* main() function */

int main(void)

{

/* variables declaration */

int x, y, z;

 

/* variables initialization - give an initial value to variable*/

/* assign 20 to variable x or put the value of 20 in memory location labeled by x */

x = 20;

y = 2;

 

/* print some info on the standard output */

printf("Given x = 20, y = 2\n");

printf("\nx / y = %d", x / y);

 

/* do some calculation */

x = x * y;

y = y + y;

 

/* print values */

printf("\nx = x * y");

printf("\ny = y + y");

printf("\nNew value for x / y = %d", x / y);

z = 20 * y / x;

printf("\nz = 20 * (y / x) = %d\n", z);

 

return 0;

}

 

Output example:

 

Given x = 20, y = 2

x / y = 10

x = x * y

y = y + y

New value for x / y = 10

z = 20 * (y / x) = 2
