Question : 1  Write a C Program to calculates the area (floating point number with two decimal places) of a Circle given it’s radius (integer value). The value of Pi is 3.14

					#include <stdio.h>
#define PI 3.14
void main()
    int radius;
    float area;
    /* Enter the radius of a circle */
    scanf("%d", &radius);
    area = PI * radius * radius;
    printf("Area of a circle = %5.2f", area);

Question : 2  Write a C program to check if a given Number is zero or Positive or Negative Using if…else statement.

					#include <stdio.h>
int main()
    double number;
    scanf("%lf", &number);
    if(number <= 0.0)
        if (number == 0.0)
            printf("The number is 0.");
            printf("Negative number.");
        printf("Positive number.");

Question : 4  Write a C Program to find the Largest Number (integer) among Three Numbers (integers) using IF and Logical && operator.

					#include <stdio.h>
int main()
    int n1, n2, n3;

    scanf("%d %d %d", &n1, &n2, &n3);
    	if( n1>=n2 && n1>=n3 )
        printf("%d is the largest number.", n1);

    if( n2>=n1 && n2>=n3 )
        printf("%d is the largest number.", n2);

    if( n3>=n1 && n3>=n2 )
        printf("%d is the largest number.", n3);
