In a computer system, the octal number is expressed in the octal numeral system while the decimal number is in the decimal numeral system. The octal number is in base 8 while the decimal number is in base 10. In this article, we will write a C++ program that converts a decimal number into an octal number. Examples of decimal numbers and their corresponding octal numbers are as follows. ... Read More

In this article, we'll show how to write a C++ program to copy strings. A string in C++ is a sequence of characters, such as letters, numbers, symbols, or anything enclosed in double quotes (e.g., "Hello"). Copying a string means transferring all characters from one string to another or making an exact copy. For example, here's how copying works: Input: "Learning C++ is fun!" Output: "Learning C++ is fun!" (This is the copied string) We can copy a string in C++ using the following methods: Using strcpy() Function ... Read More

The realpath_cache_size() function returns realpath cache size i.e. the amount of memory.Syntaxrealpath_cache_size()ParametersNAReturnThe realpath_cache_size() function returns the amount of memory realpath cache is using.Example Live DemoOutput362

The realpath_cache_get() function returns realpath cache entries. It returns an array of realpath cache entries.Syntaxrealpath_cache_get()ParametersNAReturnThe realpath_cache_get() function returns an array of realpath cache entries.Example Live DemoOutputArray ( [/home] => Array ( [key] => 4353355791257440477 [is_dir] => 1 [realpath] => /home [expires] => 1538630044 ) [/home/cg/root] => Array ( [key] => 1131813419205508649 [is_dir] => 1 [realpath] => /home/cg/root [expires] => 1538630044 ) [/home/cg/root/8944881/main.php] => Array ( [key] => 584844883037958768 [is_dir] => [realpath] => /home/cg/root/8944881/main.php [expires] => 1538630044 ) [/home/cg] => Array ( [key] => 9037225891674879750 [is_dir] => 1 [realpath] => /home/cg [expires] => 1538630044 ) [/home/cg/root/8944881] => Array ( [key] => 722006552431300374 [is_dir] => 1 [realpath] => /home/cg/root/8944881 [expires] => 1538630044 ) )

The parse_ini_string() function parses a configuration string. The function returns the settings as an associative array on success. It returns FALSE on failure.Syntaxparse_ini_string(file_path, process_sections)Parametersfile_path − The ini file to be parsed.process_sections − If set to TRUE, you will get a multidimensional array with section names and settings included.ReturnThe parse_ini_string() function returns the settings as an associative array on success. It returns FALSE on failure.Let’s say the content of our “demo.ini” is −[names] one = Anne [urls] host1 = "https://www.example1.com"ExampleOutputArray ( [one] => Anne [host1] => https://www.example1.com )Read More

In this article, we'll show how to write a C++ program to concatenate two strings. A string in C++ is a sequence of characters like letters, numbers, symbols, or anything enclosed in double quotes (e.g., "Hello"). Concatenating two strings means joining them together to form one combined string. For example, if we have two strings: str1 = "Welcome to" and str2 = "tutorialspoint!", after concatenation, the result will be: result = "Welcome to tutorialspoint!". Approaches to Concatenate Strings in C++ We can concatenate strings in C++ using different methods. Below are the approaches we will cover: ... Read More

In this article, we will write a C++ program to reverse a sentence using recursion. Reversing a sentence means changing the order of all its characters in each word, so the first character moves to the end, the last character comes to the front, and the middle characters follow in the opposite order. Let's understand this with an example: // Example 1 Input: Welcome to tutorialspoint! // After reversing the sentence Output: !tniopslairotut ot emocleW // Example 2 Input: Learning C++ with tutorialspoint is fun // After reversing the sentence Output: nuf si tniopslairotut htiw ++C gninraeL ...

In a computer system, the octal number is expressed in the octal numeral system while the decimal number is in the decimal numeral system. The octal number is in base 8 while the decimal number is in base 10. In this article, we will write a C++ program to convert an octal number to a decimal number and vice-versa. Here are some examples showing decimal numbers and their corresponding octal values: ... Read More

In this article, we'll show you how to write a C++ program to access elements of an array using pointer. A pointer is a variable that holds the memory address of another variable, allowing us to reference it directly. In other words, pointers point to a memory location and obtaining the value stored at that location is called dereferencing the pointer. By using pointers, we can access and work with array elements through their memory addresses. Let's look at a simple example: Input: An array: [10, 20, 30, 40, 50] // We'll use a pointer to access ... Read More
