C Exercises: Pictorial: Find the largest element using Dynamic Memory Allocation.

Sample Solution:

C Code:

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int i,n;
    float *element;
	printf("\n\n Pointer : Find the largest element using Dynamic Memory Allocation :\n"); 
	printf("-------------------------------------------------------------------------\n"); 	
    printf(" Input total number of elements(1 to 100): ");
    scanf("%d",&n);
    element=(float*)calloc(n,sizeof(float));  // Memory is allocated for 'n' elements 
    if(element==NULL)
    {
        printf(" No memory is allocated.");
        exit(0);
    }
    printf("\n");
    for(i=0;i<n;++i)  
    {
       printf(" Number %d: ",i+1);
       scanf("%f",element+i);
    }
    for(i=1;i<n;++i)  
    {
       if(*element<*(element+i)) 
           *element=*(element+i);
    }
    printf(" The Largest element is :  %.2f \n\n",*element);
    return 0;
}

Sample Output:

 Number 1: 5                                                                                                  
 Number 2: 7                                                                                                  
 Number 3: 2                                                                                                  
 Number 4: 9                                                                                                  
 Number 5: 8

C Programming: Tips of the Day

How to format strings using printf() to get equal length in the output?

You can specify a width on string fields, e.g.

printf("%-20s", "initialization..."); 

And then whatever's printed with that field will be blank-padded to the width you indicate.

The - left-justifies your text in that field.
