Why is the output not being displayed?

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

int max(int a,int b)
{return (a>b?a:b);
}
int main()
{int i,n;

scanf("%d",&n);

int *a=(int *)malloc(n*sizeof(int));
int *m=(int *)malloc(n*sizeof(int));



for(i=0;i<n;i++)
scanf("&d",&a[i]);

m[0]=a[0];

for(i=1;i<n;i++)
m[i]=max(m[i-1]+a[i],a[i]);

printf("%d",m[n-1]);

return 0;
}
