<\/span><\/h2>\nTo assign a value returned by a function in C++, you can follow these steps:<\/p>\n
1. **Declare a variable** of the appropriate type to store the value returned by the function.
\n2. **Call the function** and capture the returned value.
\n3. **Assign the value** returned by the function to the variable.<\/p>\n
Here’s a code example to illustrate this process:<\/p>\n
“`cpp
\n#include <\/p>\n\/\/ Function that returns an integer value
\nint calculateSquare(int num) {
\n return num * num;
\n}<\/p>\n
int main() {
\n \/\/ Declare a variable to store the returned value
\n int result;<\/p>\n
\/\/ Call the function and assign the returned value to the variable
\n result = calculateSquare(5);<\/p>\n
\/\/ Print the result
\n std::cout << \"Square of 5 is: \" << result << std::endl;\n\n\n return 0;
\n}
\n“`<\/p>\n
In the code above, a function called `calculateSquare` is defined, which takes an integer as an argument and returns its square. Inside the `main` function, a variable `result` is declared and assigned the value returned by `calculateSquare(5)`. The value is then printed to the console.<\/p>\n
By using this approach, you can easily capture and assign the value returned by a function to a variable in C++.<\/p>\n
