Hematemesis, please help.
Just give a simple example:

int max(int x,int y)

{

if(x & gt; y)

Returns x;

other

Returns y;

}

Function is to find the maximum of two numbers, and int is the return value type, that is to say, the result of calling this function is to return an integer value, max is the function name, int x, int y is the parameter table, that is, when calling this function, two numbers should be written in parentheses and the value types should correspond, all of which are integer (int). The specific calling process is as follows:

void main()

{

int a,b;

Printf ("Enter two numbers to output the maximum value, please enter two numbers:");

Scanf("%d, %d ",& i, & amp);

Printf ("maximum value: %d\n", max(a, b)););

}

I don't know whether to ask this question.
