How to Replace All Substrings in Standard Strings in C ?

Replace All Substrings in Standard Strings

In C , the standard string class does not provide a built-in method to search and replace substrings. For this task, we can use the Boost library.

Solution: Using Boost's replace_all

The Boost algorithm library provides a function called boost::replace_all that can be used for search-and-replace operations. Here's how you can use it:

#include <boost/algorithm/string.hpp>

std::string target("Would you like a foo of chocolate. Two foos of chocolate?");
boost::replace_all(target, "foo", "bar");

In this example, target is the input string. boost::replace_all takes three arguments:

• target: The input string.
• old_value: The substring to be replaced.
• new_value: The replacement string.

After the operation, target will contain the modified string with all occurrences of "foo" replaced by "bar".
