I dont understand how return statement works?

#1

#include
#include
using namespace std;

int convertStringtoInt(char *str,int len) {
if(len==1) {
return str[0]-‘0’;
}

cout << str[len-1]-'0' << endl;
return (10*convertStringtoInt(str,len-1)+str[len-1]-'0');

}

int main() {
char str[]=“1234”;

int len=strlen(str);

cout << convertStringtoInt(str,len) << endl;

return 0;

}

hello @premang
The return statement stops execution and returns to the calling function. When a return statement is executed, the function is terminated immediately at that point, regardless of whether it’s in the middle of a loop, etc.
