NPTEL Problem solving through Programming In C Week 5 All Programming Assignment Solutions | Swayam 2023. 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 2023”

Question : 1  Write a C program to count total number of digits of an Integer number (N).

				
					#include <stdio.h>
int main()
{
    int N; 
    scanf("%d",&N);
    int temp, count; 
    count=0;
    temp=N;
    while(temp>0)
    {
     	count++;
     	temp/=10;
    }
    printf("The number %d contains %d digits.",N,count);
}

Question : 2 Write a C program to check whether the given number(N) can be expressed as Power of Two (2) or not.

For example 8 can be expressed as 2^3

				
					#include <stdio.h>
int main()
{
    int N;
    scanf("%d",&N);
    int temp, flag;
    temp=N;
    flag=0;
   
    while(temp!=1)
    {
        if(temp%2!=0)
        {
            flag=1;
            break;
        }
        temp=temp/2;
    }
  
    if(flag==0)
        printf("%d is a number that can be expressed as power of 2.",N);
    else
        printf("%d cannot be expressed as power of 2.",N);
}

Question : 3  Write a C program to find the sum of following series where the value of N (Odd integer number) is taken as input 

				
					#include<stdio.h>
int main()
{
    int i,n,sum=0;
    scanf("%d",&n); 
    for(i=1;i<=n;i=i+2)
    {
      sum+=i*i;
    }
    printf("Sum=%d",sum);
    return 0;
}

Question : 4 Write a C program to print the following Pyramid pattern upto Nth row. Where N (number of rows to be printed) is taken as input.


For example when the value of N is 5 the pyramid will be printed as follows:

*****
****
***
**
*

				
					#include<stdio.h>
int main()
{
    int N;
    scanf("%d", &N);
    int i, j;
    for(i=N; i>0; i--)
    {
        for(j=0;j<i;j++)
        {
  		    printf("*");
        }
  	    printf("\n");
    } 
}
