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

int main() {
int n;
scanf("%d\n", &n);
int *arr;
arr= (int*)calloc(n, sizeof(int));
int large=*arr;
if(arr==NULL) {
printf("Memory Allocation Failed!");
}
else{
for(int i=0;i<n;i++)
{ printf("%d",i);
scanf("%d\n",arr+i);
}

for(int i=1; i<n; ++i){
if(*arr<*(arr+i))
large=*(arr+i);
}
}
printf("Largest no. is: %d", large);
return 0;
}

Answer 1

After if statement add-
else
large = *arr;
