places [concat $string " (iteration number $i)"]
}
This code will print the string "Whats up, world! (iteration quantity #)" ten occasions, the place "#" is changed by the present iteration quantity.
4. Utilizing the repeat Command
Tcl gives a built-in command referred to as repeat that can be utilized to create a string containing a specified sample repeated a sure variety of occasions. This may be useful for printing a string a number of occasions with minimal code. Here is an instance:
