NPTEL Problem solving through Programming In C Week 3 All Programming Assignment Solutions | Swayam 2022. With the growth of Information and Communication Technology, there is a need to develop large and complex software.

ABOUT THE COURSE:

This course is aimed at enabling the students to:
  • Formulate simple algorithms for arithmetic and logical problems
  • Translate the algorithms to programs (in C language)
  • Test and execute the programs and  correct syntax and logical errors
  • Implement conditional branching, iteration and recursion
  • Decompose a problem into functions and synthesize a complete program using divide and conquer approach
  • Use arrays, pointers and structures to formulate algorithms and programs
  • Apply programming to solve matrix addition and multiplication problems and searching and sorting problems 
  • Apply programming to solve simple numerical method problems, namely rot finding of function, differentiation of function and simple integration

Course Name : “Problem Solving through Programming In C 2022”

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.");
        else
            printf("Negative number.");
    }
    else
        printf("Positive number.");
}

Question : 3  Write a C program to check whether a given number (integer) is Even or Odd.

				
					#include <stdio.h>
int main()
{
    int number;
    scanf("%d", &number);
     if(number % 2 == 0)
    	printf("%d is even.", number);
    else
    	printf("%d is odd.", 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);
