how to print blank space(s) ?..

[mark]

how to print, say 50 blank spaces, or say 20 blank spaces ?

I wanted use such blank spaces that can be output in a program at
predetermined places when printing with "cout".

Use a loop

for (int i = 0; i < 50; ...

and output one space at a time

Or, declare a constant string consisting of 50 spaces and
output it.

Or, declare a constant string consisting of 5 spaces and
output it in a loop that executes 10 times.

What are you really trying to accomplish? If you want aligned output,
look into the setw family of operations on ostreams. If you really want
to output any value more than once, loop.

int main(void){
int increment;

for(increment = 1; increment <= 50; increment++){
if(!(50 % increment)){
printf("Or, declare a constant string \
consisting of %i spaces and\noutput it in a loop that executes %i \
times.\n\n", increment, 50 / increment);
}
}
return 0;
}

cout << setw(50) << " ";

std::cout << std::string(50, ' ');

std::cout << std::string(20, ' ');

The only way you can 'predetermine' where the output goes
is to keep track of how many characters you've printed
so far on each line. There is no way to specify a
vertical position to print on a video device. I/O in
C++ is only in terms of 'streams of characters'.
