Problem Solving Through Programming in C

Week-05 Problem-01

Due Date of Submission 2022-03-03, 23:59 IST

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);

--Solution-- 

  int count=0,t; t=N; do { t/=10; count+=1; }while(t!=0); printf("The number %d contains %d digits.", N, count); return 0; }

Week-05 Problem-02

Due Date of Submission 2022-03-03, 23:59 IST

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

#include<stdio.h>

int main()

{

int N;

float sum = 0.0;

scanf("%d",&N);

--Solution-- 

  float i,a; for(i=1;i<=N;i++){ a=(1/i); sum+=a; } printf("Sum of the series is: %.2f\n", sum); return 0; }

Week-05 Program-03

Due Date of Submission 2022-03-03, 23:59 IST

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);

--Solution-- 

  int i,j; for(i=N;i>=1;i--){ for(j=1;j<=i;j++){ printf("*"); } printf("\n"); } return 0; }

Week-05 Program-04

Due Date of Submission-03, 23:59 IST

Write a C [rogram to find sum of following series where the value of N (odd integer number) is taken as input

12+32+52+…+n2

#include<stdio.h>
int main()
{
int n, sum=0;
scanf("%d",&n);

--Solution-- 

  int a,i; for(i=1;i<=n;i=i+2){ a=i*i; sum+=a; } printf("Sum = %d",sum); return 0; }
