This tutorial will discuss about unique ways to check if a string contains only digits in C++. Technique 1: Using STL Algorithm std::all_of() To check if string has only digits we can use the STL algorithm all_of(). t accepts three arguments, The all_of() function will apply the ::isdigit() function on all the characters in string. […]

This tutorial will discuss about unique ways to check if two strings are equal in C++. Technique 1: Using == Operator We can directly apply the == operator on two string objects, to confirm if these two string objects are equal or not. By equal, we mean the both the string objects contains the same

This tutorial will discuss about a unique way to check if a string can be converted to a double in C++. To check if a string contains a valid double value or not, we can try to convert the string into a double using stod() function. If the conversion is successful, then we can confirm

This tutorial will discuss about unique ways to check if a string can be converted to an int in C++. Technique 1: Check if string can be converted to an integer We can use the stoi() function to convert a string into an integer. If the string contains a valid integer i.e. digits only, then

This tutorial will discuss about a unique way to get string before a character in C++. To get a substring before a specific character in a string, first we need to check if the given character exists in the string or not. If string contains the specified character, then we need to fetch its index

This tutorial will discuss about a unique way to check if a string is binary in C++. To check if a string contains a Binary value or not, we need to confirm if string contains only 0s or 1s. For that, we can use the STL Algorithm all_of(). we will pass following arguments in it,

This tutorial will discuss about unique ways to get string between two characters in C++. Suppose we have a string, and we want to get a substring from this main string. We will have two characters, and we need to fetch a substring between these two specific characters from the main string. For example, The

This tutorial will discuss about unique ways to count number of characters in a string array in C++. Suppose we have a string array, like this, Now we want to count the total number of characters in this string array. For that, we need to iterate over all string objects in this array, and count

In this article, we will disucss different ways to find and replace any substring in a given string with another string in C++. Using a char array and pointer arithmetic: We will be using the following functions in the program: memcpy(): The memcpy() is a C-style function that copies a specified number of bytes from

In this article, we will discuss different ways to replace a character in string at a particular index in C++. Table Of Contents Introduction Case 1: The index of the character to be replaced and the new character are given as input. Using std::string::replace() Using the [] operator Case 2: The character to be replaced
