please, I want a help in this program:
Write a program to ask the user to enter the total number of bytes he or she wants to allocate. Then, initialize the allocated memory with consecutive integers, starting from 1. Add all the integers contained by the memory block and print out the final result on the screen.
I made the following code:
#include<stdio.h>
#include<stdlib.h>
main()
{
int bytes;
int *ptr;
printf("please, enter the number of bytes to allocate\n");
scanf("%d\n",&bytes);
ptr= malloc (bytes * sizeof(int));
if(ptr==NULL)
{
printf("memory allocation failed!\n");
}
else {
int i=0;
for(i=0;i<bytes;i++)
ptr
=i+1;
int j,sum=0;
for(j=0;j<bytes;j++)
sum+=ptr[j];
printf("sum of number from 1 to %d = %d\n",bytes,sum);
return 0;
}
}
but i had this error: error C2440: '=' : cannot convert from 'void *' to 'int *'
Conversion from 'void*' to pointer to non-'void' requires an explicit cast
Error executing cl.exe.
can any one help??
