What should I do to add an integer to an hex string.
Say my hex string is:
11'h000
And I want to add integer 7 to it. Output it should give should be
11'h007
If given 11'h00e, Adding integer 1 to it should give me 11'h00f.
Are there any predefined functions in c++? I could have write my switch-case statements to get it but looking for a compact way.
The best way? Don't confuse formatting of a number with a number.
Use
int x = std::stoi(s/*a hexadecimal string*/, nullptr, 16 /*hexadecimal*/);
x++; /*all your arithmetic operations here*/
std::cout/*or a suitable stream*/ << std::hex << x;
