#include<string>

size_t count_spaces(std::string& str)

{

size_t spaces=0;

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

if( str[i]==32 )

++spaces;

return( spaces );

}

int main()

std::string str("This is a string with some spaces.");

size_t spaces = count_spaces(str);

std::cout<<"The string ""<<str.c_str()<<"" has "<<spaces<<" spaces.\n"<<std::endl;
