I'm trying to build a manually "atoi" function without the <string> library

Question

so far here is were I got which works only for one digit

#include<iostream>
using namespace std;

int myAtoi(int someChar) {
int num = someChar - 48;
return num;
}

int main()
{
char aChar;
cin >> aChar;
cout << myAtoi(aChar);
return 0;
}

any ideas for a char[]? (avoiding the string)

Answer 1

int yourAtoi(char[] someString){
//do sth here
return sth;
}
int main(){
char num[]="1234";
cout<<yourAtoi(num);
}
👍
