Question

Read From Input Until EOF and Display Total Number of Integers (C++).

1. Input a line of string. For example: I have 2 sons and 4 daughters.

Expected output will be the total number of integers in the strings which is 2.

2. Input multiple line of string. For example:

Line 1: I have 2 sons and 4 daughters.

Line 2: My daughters have 2 cars.

Expected output should be 3.

Thanks in advance.

using namespace std;

int main() {

string str;

int count = 0;

while (1) {

getline(cin, str);

if (str == "") {

break;

}

for (int i=0; i<str.size(); i++) {

if (str[i] >= '0' && str[i] <= '9') {

count ++;

}

}

}

cout << count;
