C program to read the values of x, y and z and print the results expressions in one line.

#include

#include

void main()

{

    int x, y, z;

    float a, b, c;

    clrscr();

    printf("\nEnter the values of x,y and z : ");

    scanf("%d %d %d", &x, &y, &z);

    a = (x + y + z) / (x - y - z);

    b = (x + y + z) / 3;

    c = (x + y) * (x - y) * (y - z);

    printf("\nValue of a = %f",a);

    printf("\nValue of b = %f",b);

    printf("\nValue of c = %f",c);

    getch();

}

Output

Enter the values of x,y and z : 1.1 2.5 5.5

Value of a = -1.000000

Value of b = 2010.000000

Value of c = 27939.000000

C program to reads customer number and power consumed and prints amount to be paid

#include

#include

 void main()

{

   int cust_no, powerUsage;

   float amount;

   clrscr();

   printf("Enter the customer number: ");

   scanf("%d", &cust_no);

   printf("Enter the power consumed: ");

   scanf("%d", &powerUsage);

   if (powerUsage >= 0 && powerUsage <= 200)

      amount = powerUsage * 0.50;

   else if (powerUsage > 200 && powerUsage < 400)

      amount = 100 + ((powerUsage - 200) * 0.65);

   else if (powerUsage > 400 && powerUsage <= 600)

      amount = 230 + ((powerUsage - 400) * 0.80);

   printf("Amount to be paid by customer no. %d is Rs.:%5.2f.", cust_no, amount);

   getch();

}

Output

Enter the customer number: 1

Enter the power consumed: 100

Amount to be paid by customer no. 1 is Rs.:50.00.

C Program to demonstrates binary expressions using floating-point arithmetic

#include

#include 

int main()

{

   float a = 14.0;

   float b = 5.0;

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

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

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

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

   return (0);

}

Output

14.000000 + 5.000000 = 19.000000

14.000000 - 5.000000 = 9.000000

14.000000 * 5.000000 = 70.000000

14.000000 / 5.000000 = 2.800000

C Program to demonstrates binary expressions using integer arithmetic

#include

#include

int main()

{

   int a = 5;

   int b = 5;

   printf("%d + %d = %d \n", a, b, a + b);

   printf("%d - %d = %d \n", a, b, a - b);

   printf("%d * %d = %d \n", a, b, a * b);

   printf("%d / %d = %d \n", a, b, a / b);

   printf("%d %% %d = %d\n", a, b, a % b);

   return(0);

}

Output

5 + 5 = 10

5 - 5 = 0

5 * 5 = 25

5 / 5 = 1

5 % 5 = 0

C Program to find greatest in 3 numbers

#include

#include

int main()

{

   int a, b, c;

   printf("\nEnter value of a, b & c : ");

   scanf("%d %d %d", &a, &b, &c);

   if ((a > b) && (a > c))

      printf("\na is greatest");

    if ((b > c) && (b > a))

      printf("\nb is greatest");

    if ((c > a) && (c > b))

      printf("\nc is greatest");

    return(0);

}

Output

Enter value for a,b & c : 15 17 21

c is greatest

C Program to calculate gross salary of a person

#include

#include 

int main()

{

   int gross_salary, basic, da, ta;

   printf("Enter basic salary : ");

   scanf("%d", &basic);

   da = (10 * basic) / 100;

   ta = (12 * basic) / 100;

   gross_salary = basic + da + ta;

   printf("\nGross salary : %d", gross_salary);

   return (0);

}

Output

Enter basic Salary : 1000

Gross Salart : 1220
