1. WRITE A PROGRAM THAT INPUTS 4 NUMBERS AND CALCULATES THE SUM, AVERAGE   AND PRODUCT OF ALL THE
   NUMBERS.
   

#include

#include

main( )

{

int a,b,c,d,sum,avg,prod;

printf("enter the four numbers");

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

sum=a+b+c+d;

avg=sum/4;

prod=a*b*c*d;

printf("the sum is %d \n",sum);

printf("the average is  %d \n",avg);

printf("the product is %d \n",prod);

getch();

}

 Enter the four numbers , 2 ,4,5,6

OUTPUT

The sum is =17

The average is = 4.25

The Product is =240

1. WRITE A PROGRAM THAT INPUTS BASE AND HEIGHT FROM THE USER AND CALCULATES AREA OF TRIANGLE BY USING THE (FORMULA AREA=12*BASE*HEIGHT)

#include

#include
void main()

{

int base,height,area;

printf(“enter the base and height “);

scanf(“%d%d”,&base,&height);

area= 0.5*base*height;

printf(“the area of triangle is %d “,area);

getch();

}

Enter the base and height 5,4

OUTPUT

The area of triangle is 10

3-WRITE A PROGRAM THAT INPUTS A NUMBER AND FINDS WHETHER IT IS EVEN OR ODD USING IF-ELSE STRUCTURE.

#include

#include

void main()

{

int num;

printf(“enter the number”);

scanf(“%d”,&num);

if(num%2==0)

printf(“the number is even %d“,num);

else

printf(“the number is odd %d”,num);

getch();

}

Enter the number 3

OUTPUT

The number is even

4-WRITE A PROGRAM THAT INPUTS A NUMBER OF WEEKDAYS AD DISPLAYS THE NAME OF THE DAY USING SWITCH STATEMENT.

#include

#include

void main()

{

int num;

printf(“enter the number “);

scanf(“%d”,&num)

switch(num)
{

case 1:

printf(“SUNDAY”);

break;

case 2:

printf(“MONDAY”);                                                                 enter the number, 4

break;

case 3:

printf(“TUESDAY”);                                                                               OUTPUT

break;

case 4:

printf(“WEDNESDAY”);                                                                       WEDNESDAY

break;

case 5:

printf(“THURSDAY”);

break;

case 6:

printf(“FRIDAY”);

break;

case 7:

printf(“SATURDAY”);

break;

default :

printf(“enter correct number “);

}

getch();

}

5-        WRITE A PROGRAM THAT INPUTS A YEAR AND CHECK WHETHER IT IS A LEAP YEAR OR NOT USING IF-ELSE .

#include

#include

void  main()

{

int year;

printf(“enter the year “);

scanf(“%d”,&year);

if(year%4==0)

printf(“the year is a leap year %d”,year);

else

printf(“the year is a normal year %d”,year);

getch();

}

                 Enter the year ,2015

                   OUTPUT

The year is a normal year

6-WRITE A PROGRAM THAT DISPLAYS FIRST TEN NUMBERS AND THEIR AVERAGE USING DO..WHILE LOOP.

#include

#include

void main()

{

int sum=0, j,avg;

do

{

printf(“%d”,j);

j++;

sum=sum+j;

}while(j<=10);

avg=sum/10;

printf(“the average is %d”,avg);

getch();

}

OUTPUT

012345678910th average is 6
