what is the problem with this code??

#include<stdio.h>
int main()

scanf(“%s%d”,&p[i],&a[i]);
}
scanf(“%lld”,&m);

if(p[i]==‘a’)m-=a[i];
else if(p[i]==‘s’)m+=a[i];
else if(p[i]==‘m’)m/=a[i];
else if(p[i]==‘d’)m*=a[i];
}
printf(“%lld”,m);

ain’t you mistaking characters with strings?

char p[n]; // p is declared as a string here.

for (i = 0; i < n; i++){
