ARM example to demonstrate the assembly function call from C program

/* Assignment - 3 */
#include<stdio.h>
#define SIZE 1000
int main()
{
	int i,sourceAddr,destinationAddr,lengthOfData;
	char memory[SIZE];
	printf("\n enter the souce Addr, Destination addr, and the length of data:");	
	scanf("%d%d%d",&sourceAddr,&destinationAddr,&lengthOfData);	
	for(i=0;i<20;i++)
		memory[i]=i+65;	
	MemCopy(memory+sourceAddr,memory+destinationAddr,lengthOfData);
	printf("\n returned from assembly code");
	for(i=0;i<70;i++)
		printf("\t mem[%d]=%c",i,memory[i]);
