C++ problem
Write a function in C++ that is similar to the split() function in Python. Chop(...) is given a string and a separator character as parameters and returns an integer result. The function will print each substring of the given string between separator characters. The function returns the number of substrings printed.
For example: Chop("cow,chicken,fish") would return 3 and the output displayed on the console would be:
Hint: Remember that you can cast the unsigned integer returned by the string function length() to an integer. (e.g. int_value < (int)str.length() )
Explanation / Answer
#include <iostream>
using namespace std;
int Chop(string s){
int count = 1;
string str = "";
for(int i=0; i<s.length(); i++){
if(s[i] == ','){
count++;
cout<<str<<endl;
str = "";
}
else{
str = str + s[i];
}
}
cout<<str<<endl;
return count;
}
int main()
{
string s;
cout << "Enter the string: ";
cin >> s;
int count = Chop(s);
cout<<"Result = "<<count<<endl;
return 0;
}
Output:
sh-4.2$ g++ -o main *.cpp
sh-4.2$ main
Enter the string: cow,chicken,fish
cow
chicken
fish
Result = 3
