Problem Solving Through Programming In C Programming Assignment
Question 1
Write a C program to count total number of digits of an Integer number (N).
Solution:
int temp, count;
count=0;
temp=N;
while(temp>0)
{
count++;
temp/=10;
}
printf("The number %d contains %d digits.",N,count);
}Question 2
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.
Solution:
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);

Question 3
Write a C program to find sum of following series where the value of N (odd integer number) is taken as input
123252+….+n2?
Solution:
for (i = 1; i <= n; i += 2) {
sum += i * i;
}
printf("Sum=%d\n", sum);
return 0;
}Question 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
*****
****
***
**
*
Solution:
int i,j;
for(i=N; i>0; i--)
{
for(j=0;j<i;j++)
{
printf("*");
