The application scope analysis of the IF statement of VC + + _c language

The example of this article succinctly illustrates the application scope of if in VC + +, through a section of If program code to explain the law of if statement execution, to go down in detail to see this simple test code:

# include <stdio.h>
int main (void)
{
 if (1 > 2)
 printf ("aaaa\n");
 printf ("bbbb\n");
 return 0;
}

I believe a lot of readers will think that the program is running at 0, and in fact the output of the program code in vc++6.0 is: bbbb.

It can be seen thatif the default case can only control the execution of a statement or not to execute, but not to select a statement to execute, generally to execute the most subsequent statements.

It is hoped that the example described in this paper can help readers to understand the principle and usage of the IF statement in VC + +.
