string

[mar11]

Hi all,

how can i add a variable number of spaces in string,

for example:

int i (7);
string st1 = "example1";
string st2 = "example2"
st1 +=  "      ";  ?? what i ve to write to get the number of spaces prameterized??
st1 += st2  // outpot --  example1      example
 

how can i declare the number of desired space in string ??

thank a lot...

Create another string with the correct number of spaces and append that string to st1.

this solution will not help me...

Actually, the number of sapces i have to calulate in the programm, so sometimes 8 space tabs anothertime 20, it depends on code.

Now, i want to change this number of spaces (8,..., 20) as a string (" " or " ") and so on...


thank for each advance..

Of course my suggestion will work:

Write a function that returns a string. Inside the function calculate the number of spaces and build a string that long. Return that string.

Then append the string the function returns to st1.

thanks for each advice

Calculate the number of spaces. Say, 28. Then run a loop 28 times that appends one space to a newly created string.
