Nettet2 dager siden · When programming, we often need constant variables that are used within a single function. For example, you may want to look up characters from a table. The following function is efficient: char table(int idx) { const char array[] = {'z', 'b', 'k', 'd'}; return array[idx]; } It gets trickier if you have constants that require … Continue reading … Nettet13. apr. 2024 · The strlen () function is a commonly used function in C++ that allows you to determine the length of a C-style string.

Suppose X and Y are two operands, this plus operators will … Nettet13. apr. 2024 · The remainder operator (also commonly called the modulo operator or modulus operator) is an operator that returns the remainder after doing an integer division. For example, 7 / 4 = 1 remainder 3. Therefore, 7 % 4 = 3. As another example, 25 / 7 = 3 remainder 4, thus 25 % 7 = 4. The remainder operator only works with integer operands.

By iterating through the characters in the string and counting them until it reaches the null character '\0', the function returns the length of the string as a size_t value. While strlen () is a useful tool for working with C ...
