Nptel Week 5 Programming Assignment Answers:

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

Code:

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

Q.2: 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

Code:

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

Q.3: 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.

Code:

int t=N,flag=0,num; while(t!=0){ t/=2; if(t%2!=0 && t!=1){ flag=1; break; } else{ flag=0; } } 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); } return 0; }

Q.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

Code:

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