I have strings such as:
var abc = "Menu Link"; Is there a simple way I can change the space to an underscore?

Use the String. replaceAll method to replace all spaces with underscores in a JavaScript string, e.g. string. replaceAll(' ', '_') . The replaceAll method returns a new string with all whitespace characters replaced by underscores.
Replacing space with a hyphen in C++ In this C++ program, the space in the string will be replaced with the hyphen. Firstly, the length of the string is determined by the length() function of the cstring class, then hyphen is filled into the space of the sentence by traversing the string as follows.
Approach: Count the total spaces in a string in one iteration, say the count is spaceCount. Calculate the new length of a string by newLength = length + 2*spaceCount; (we need two more places for each space since %20 has 3 characters, one character will occupy the blank space and for rest two we need extra space)
If you want to do it in place:
abc = abc.Replace(" ", "_"); Although do realize a new string instance will be created; it's not actually done in the same memory location - String is an immutable type.
