Week 5 Solutions

Programming Assignment :

Week-05: Program-01 :

Write a C program to check whether a given number (N) is a perfect number or not? [Perfect Number - A perfect number is a positive integer number which is equals to the sum of its proper positive divisors.
For example 6 is a perfect number because its proper divisors are 1, 2, 3 and it’s sum is equals to 6.]

int i, sum=0;
    for(i=1; i<N;i++)
    {
        if(N%i==0)
            sum+=i;
    }
 
    if(sum==N)
        printf("\n%d is a perfect number.",N);
    else
        printf("\n%d is not a perfect number.",N);
}

Week-05: Program-02 :

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

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

Week-05 Program-03 :

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

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);
}

Week-05 Program-04 :

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

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

CRITERIA TO GET A CERTIFICATE :
  1. Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
  2. Exam score = 75% of the proctored certification exam score out of 100
  3. Final score = Average assignment score + Exam score
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met,you will not get the certificate even if the Final score >= 40/100.
