How to write a programme which counts letter 'a'?

tinuviel2006 (2)
Hey guys, I'm rather new to programming, and I have an assignment to write a programme with
char a[20]
and the user needs to insert a sentance
the programme needs to count the letter 'a'

I've tried to solve this several times, but something always goes wrong!
Any help or suggestion is more than welcome!

#include <iostream>
using namespace std;
int main(){
    char a[20];
    int i;
    cin>>a;
    for (i=0; i<=20; i++){
    if (a[i]=='a'){
                cout<<"Number of letter 'a' is: "<<a[i]<<endl;
                }
                
    else cout<<"The sentance doesn't contain letter 'a'"<<endl;
}
    
    
    system("PAUSE");
    return 0;
}
