How to call a function to output int function return value in c++
To call a function in C and output its int return value: Declare and define a function that returns an int value. Call the function in the main function and store the return value in a variable, then print the value of the variable using the std::cout stream outputter.
How to call a function in C to output int function return value
In C, call a function and output it The process of returning an int value is very simple.
Step 1: Declare and define a function that returns an int value
int myFunction() { // 函数主体 return value; }
Step 2: Call the function in the main function
int main() { int result = myFunction(); std::cout << result << std::endl; return 0; }
Through the above steps, you can call the function in C and output its int return value.
Detailed explanation:
- int myFunction(): This is a function declaration that returns an int type value.
- return value: The function returns an int value through the return statement.
- int result = myFunction(): Call the function in the main function and store the return value in the result variable.
- std::cout << result << std::endl: Use the std::cout stream outputter to print the value of the result variable.
Sample code:
#include <iostream> int myFunction() { return 10; } int main() { int result = myFunction(); std::cout << result << std::endl; // 输出 10 return 0; }
The above is the detailed content of How to call a function to output int function return value in c++. For more information, please follow other related articles on the PHP Chinese website!

In C++ concurrent programming, the concurrency-safe design of data structures is crucial: Critical section: Use a mutex lock to create a code block that allows only one thread to execute at the same time. Read-write lock: allows multiple threads to read at the same time, but only one thread to write at the same time. Lock-free data structures: Use atomic operations to achieve concurrency safety without locks. Practical case: Thread-safe queue: Use critical sections to protect queue operations and achieve thread safety.

C++ object layout and memory alignment optimize memory usage efficiency: Object layout: data members are stored in the order of declaration, optimizing space utilization. Memory alignment: Data is aligned in memory to improve access speed. The alignas keyword specifies custom alignment, such as a 64-byte aligned CacheLine structure, to improve cache line access efficiency.

Implementing a custom comparator can be accomplished by creating a class that overloads operator(), which accepts two parameters and indicates the result of the comparison. For example, the StringLengthComparator class sorts strings by comparing their lengths: Create a class and overload operator(), returning a Boolean value indicating the comparison result. Using custom comparators for sorting in container algorithms. Custom comparators allow us to sort or compare data based on custom criteria, even if we need to use custom comparison criteria.

The steps to implement the strategy pattern in C++ are as follows: define the strategy interface and declare the methods that need to be executed. Create specific strategy classes, implement the interface respectively and provide different algorithms. Use a context class to hold a reference to a concrete strategy class and perform operations through it.

Golang and C++ are garbage collected and manual memory management programming languages respectively, with different syntax and type systems. Golang implements concurrent programming through Goroutine, and C++ implements it through threads. Golang memory management is simple, and C++ has stronger performance. In practical cases, Golang code is simpler and C++ has obvious performance advantages.

C++ smart pointers implement automatic memory management through pointer counting, destructors, and virtual function tables. The pointer count keeps track of the number of references, and when the number of references drops to 0, the destructor releases the original pointer. Virtual function tables enable polymorphism, allowing specific behaviors to be implemented for different types of smart pointers.

There are three ways to copy a C++ STL container: Use the copy constructor to copy the contents of the container to a new container. Use the assignment operator to copy the contents of the container to the target container. Use the std::copy algorithm to copy the elements in the container.

C++ multi-threaded programming implementation based on the Actor model: Create an Actor class that represents an independent entity. Set the message queue where messages are stored. Defines the method for an Actor to receive and process messages from the queue. Create Actor objects and start threads to run them. Send messages to Actors via the message queue. This approach provides high concurrency, scalability, and isolation, making it ideal for applications that need to handle large numbers of parallel tasks.
