Simple calculation Program (Addition, Subtraction, Multiplication, Division)

Sum of two numbers

#include <stdio.h>

#include <conio.h>

int main()

{

   int a, b, sum;

printf("Enter the first number: ");

scanf("%d",&a);

printf("Enter the second number: ");

scanf("%d",&b);

//printf("Enter two no: ");

//scanf("%d %d", &a, &b);

sum = a + b;

printf("Sum : %d", sum);

return(0);

}

Output

Enter the first number: 5

Enter the second number: 6

Sum : 11

Subtraction of two numbers

#include <stdio.h>

int main()

{

   int a, b, Substraction;

printf("\nEnter two no: ");

scanf("%d %d", &a, &b);

Substraction = a - b;

printf("Result : %d", Substraction);

return(0);

}

Output

Enter two no: 8    2

Result : 6

Multiplication of two numbers

#include <stdio.h>

int main()

{

   int a, b, Multiplication;

printf("\nEnter two no: ");

scanf("%d %d", &a, &b);

Multiplication = a * b;

printf("Result : %d", Multiplication);

return(0);

}

Output

Enter two no: 8    2

Result : 16

Division of two numbers

#include <stdio.h>

int main() 

{

   int a, b, Division;

printf("\nEnter two no: ");

scanf("%d %d", &a, &b);

Division = a / b;

printf("Result : %d", Division);

return(0);

}

Output

Enter two no: 8    2

Result : 4

Addition, Subtraction, Multiplication, Division of two numbers(Single Program)

#include <stdio.h>

int main() {

    // printf() displays the string inside quotation

     

     float a,b;

printf("Enter the two numbers: ");

scanf("%f %f", &a, &b);

printf("sum = %f",(a+b));

printf("\nsub = %f",(a-b));

printf("\nmul = %f",(a*b));

printf("\ndiv = %f",(a/b));

return 0;

}

Output

Enter the two numbers: 15  2

sum = 17.000000

sub = 13.000000

mul = 30.000000

div = 7.500000
