The function uses *num to access and modify the actual variable a in main(). After the function call, the value of a is updated to 20. Recursive Functions in C A recursive function is a function that calls itself in order to solve smaller instances of a problem. Each recursive call wor...
And in general, the ceil function is used in parallel with the floor function. These functions precisely give the integer value concerning the lower and higher value for the floating-point number provided in the parameter. Examples of ceil function in C++ Let us see different examples in getting...
In this tutorial, we will learnfunctions in C programming. A function is ablock of statementsthat performs a specific task. Let’s say you are writing a C program and you need to perform a same task in that program more than once. In such case you have two options: a) Use the same...
String function are the functions that are used to perform operations on a string. C++ uses <string.h> library to provides various string functions like strcat, strlen, strcmp, strcpy, swap, and many more where strcat is used to concatenate string, strlen will calculate the length of the str...
For instance, in order to use mathematical functions such as sqrt() and abs(), we need to include the header file cmath. Example 5: C++ Program to Find the Square Root of a Number #include <iostream> #include <cmath> using namespace std; int main() { double number, squareRoot; nu...

Inline functions are particularly useful for small, frequently called functions, as they can help minimize the performance cost of function invocation. One of the main advantages of the inline function in C++ is that it can also be used with C++ classes. Syntax For Defining An Inline Function ...
