Question

I need its answer as soon as possible.

Write a C program that uses malloc to find the sum on a 1-D int array that holds 1000 integers, incriminating from 1. Also share the output and discuss what you have learned to complete the task.

Answer 1

#include <stdio.h>
#include <stdlib.h>

#define N 1000

int main()
{
int n , i , *ptr , sum = 0;

ptr = (int*) malloc(N * sizeof(int));
if(ptr == NULL)
{
printf("Memory not allocated");
exit(1);
}

for(i = 0 ; i < N; ++i)
{
   *(ptr + i) = i + 1;
sum += *(ptr + i);
}

printf("Sum = %d", sum);
free(ptr);
   return 0;
}

:- And we learn with help of this task ,how to use malloc. And also know importance of malloc.
