Description

Prog1 : Write a program to find addition of two numbers. #include #include void main() { int a,b,c; printf("\nEnter values of a and b:\n"); scanf("%d%d",&a,&b); c=a+b; printf("Addition=%d",c); getch(); } Output

Prog.2 :Write a program to calculate the area of circle. #include #include void main() { float r,area,pie=3.14; printf("\nEnter the radius of the circle:\n"); scanf("%f",&r); area=pie*r*r; printf("Area of circle is%f",area); getch(); }

Output

Prog.3 : Write a program to calculate the circumference of circle. #include #include void main() { float r,circumference,pie=3.14; printf("\nEnter the radius of the circle\n"); scanf("%f",&r); circumference=2*pie*r; printf("Circumerence of circle is%f",circumference); getch(); }
