How to return multiple values from a function in C/C++?

In C or C, we cannot directly return multiple values from a function. In this section, we will see how to return multiple values from a function using some tricks.

We can use the "call by address" method to return multiple values from a function, or "call by reference". In the calling function we will use two variables to store the result and the function will take pointer type data. So we have to pass the address of the data.

In this example, we will see how to define a function that returns the quotient and remainder from a function after dividing two numbers.

#include void div(int a, int b, int *quotient, int *remainder) { *quotient = a / b; *remainder = a % b; } main() { int a = 76, b = 10; int q, r; div(a, b, &q, &r); printf("Quotient is: %d\nRemainder is: %d\n", q, r); }

Output

Quotient is: 7 Remainder is: 6
