Problem Solving through Programming In C Jan 2024
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.]
#include <stdio.h>
int main()
{
int N;
scanf("%d",&N);
int i, sum=0;
for(i=1; i<N;i++)
{
if(N%i==0)
sum+=i;
}
if(sum==N)
printf("%d is a perfect number.",N);
else
printf("%d is not a perfect number.",N);
}

Program-02 : 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);
int temp, count;
count=0;
temp=N;
while(temp>0)
{
count++;
temp/=10;
}
printf("The number %d contains %d digits.",N,count);
}

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.
#include <stdio.h>
int main()
{
int N;
scanf("%d",&N);
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);
}

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