What will be the program to print the number of spaces in a string

Question

using if statement

Answer 1

i think you could study the string functions like isspace() .

int y=0;

for(x=0;x<str.length;x++)
if(isspace(str[x]))

/* it s a bit different from str[x]==' ' */

y++;
cout<<y;

edit: you can use the number in the ASCII table instead of ' '. :))

here my c++ code:
#include <iostream>
#include<string>
using namespace std;

cout<<s[i];
cout<<" ";
}

return 0;
