How to remove all the occurrences of a char in c++ string
c++, stl
Solution
Basically, `replace` replaces a character with another and `''` is not a character. What you're looking for is `erase`.
See this question which answers the same problem. In your case:
#include <algorithm>
str.erase(std::remove(str.begin(), str.end(), 'a'), str.end());
Or use `boost` if that's an option for you, like:
#include <boost/algorithm/string.hpp>
boost::erase_all(str, "a");
All of this is well-documented on reference websites. But if you didn't know of these functions, you could easily do this kind of things by hand:
std::string output;
output.reserve(str.size()); // optional, avoids buffer reallocations in the loop
for(size_t i = 0; i < str.size(); ++i)
if(str[i] != 'a') output += str[i];
Problem
I am using following: ``` replace (str1.begin(), str1.end(), 'a' , '') ``` But this is giving compilation error.
