Problem Solving Through Programming in C

Week-03: Program-01

Due Date of Submission 2022-02-17, 23:59 IST

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.
[Marks for Week 3 Programming assignments will not be evaluated finally. This is for users to get familiar with programming in google course builder platform]

#include <stdio.h>

#define PI 3.14

void main()

{

    int radius;

    float area;

    /* Enter the radius of a circle */

    scanf("%d", &radius);

--Solution-- 

  area=3.14*radius*radius;

printf("Area of a circle = %5.2f\n", area);
}

Week-03: Program-02

Due Date of Submission 2022-02-17, 23:59 IST

Write a C program to check if a given Number is zero or Positive or Negative Using if...else statement.
[Week 3 programming assignments will not be considered for final evaluation]

#include <stdio.h>

int main()

{

    double number;

    scanf("%lf", &number); 

--Solution-- 

  if(number>0){ printf("Positive number.");} else{ if(number<0){ printf("Negative number.");} else{ printf("The number is 0."); } } }

Week-03: Program-03

Due Date of Submission 2022-02-17, 23:59 IST

Write a C program to check whether a given number (integer) is Even or Odd.
[This program does not carry any marks.]

#include <stdio.h>

int main()

{

    int number;

    scanf("%d", &number);

--Solution-- 

  if(number%2==0){ printf("%d is even.", number);} else{ printf("%d is odd.", number); } }

Week-03: Program-04

Due Date of Submission 2022-02-17, 23:59 IST

Write a C Program to find the Largest Number (integer) among Three Numbers (integers) using IF and Logical && operator.
[Week 3 programming assignments will not be considered for final evaluation]

#include <stdio.h>

int main()

{

    int n1, n2, n3;

    scanf("%d %d %d", &n1, &n2, &n3);

--Solution-- 

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