Week-05 Program-01

Last Day of Submission: 1-Sep-2022

Write a C program to count total number of digits of an Integer number N.

--Solution-- 

  /*#include <stdio.h> int main() { int N; scanf("%d",&N);*/ int count=0,a=N; while(a!=0){ a/=10; count+=1; } printf("The number %d contains %d digits.",N,count); return 0; }

Week-05 Program-02

Last Day of Submission: 1-Sep-2022

Write a C program to find sum of following series where the value of N is taken as input
 1+ 1/2 + 1/3 + 1/4 + 1/5 + .. 1/N

--Solution-- 

  /*#include<stdio.h> int main() { int N; float sum = 0.0; scanf("%d",&N);*/ for(float i=1; i<=N;i++){ sum=sum+(1/i); } printf("Sum of the series is: %.2f\n",sum); return 0; }

Week-05 Program-03

Last Day of Submission: 1-Sep-2022

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

--Solution-- 

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

Week-05 Program-04
