Question 1

Write a program in C to find the factorial of a given number using pointers.

Solution:

void findFact(int n, long int *f)
		{
        int i;

       *f =1;
       for(i=1;i<=n;i++)
       *f=*f*i;
       }

Question 2

Write a C program to print the Record of the Student Merit wise. Here a structure variable is defined which contains student rollno, name and score.

Solution:

struct student temp;
int j;
for(i=0;i<n-1;i++)
{
for(j=0;j<n-1;j++)
{
if(s[j].score<s[j+1].score)
{
temp=s[j];
s[j]=s[j+1];
s[j+1]=temp;
}
}
}

Question 3

Write a C program to store n elements using Dynamic Memory Allocation – calloc() and find the Largest element.

Solution:

element = (float*) calloc(n, sizeof(float));

    if(element == NULL)
    {
        printf("Error!!! memory not allocated.");
        exit(0);
    }

    // Stores the number entered by the user.
    int i;
    for(i = 0; i < n; ++i)
    {
        scanf("%f", element + i);
    }

 // find the largest
    for(i = 1; i < n; ++i)
    {
       if(*element < *(element + i))
         *element = *(element + i);
    }


    printf("Largest element = %.2f\n", *element);

    return 0;
}
