/* Complete the rest of the code. Please use the printf statements as below by just changing the variables used in your program

printf(“The number %d contains %d digits.”, N, count);

int num = N, count = 0; while(num > 0) { num = num / 10; count++; } printf(“The number %d contains %d digits.”, N, count); return 0; }

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); /*Read the value of N from test cases provided*/

/* Complete the program. Please use the printf statement given below:

printf(“Sum of the series is: %.2f\n”, sum);

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

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); /*The value of N is taken as input from the test case */

for(int i=N; i>0; i–) { for(int j=1; j<=i; j++) { printf(“*”); } printf(“\n”); } return 0; }

Write a C program 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); //Value of n is taken from the test cases

for(int i=1; i<=n; i=i+2){ sum += i*i; } printf(“Sum = %d”, sum);

return 0; }
