Robustness _ weird string _ custom variable parameters

Robustness is the robustness of the system. It is the key to system survival in exceptional and dangerous situations. For example, whether a computer software fails to crash or crash when input errors, disk faults, network overload, or intentional attacks are detected is the robustness of the software. The so-called "robustness" means that the control system maintains certain performance characteristics under a certain (structure, size) parameter disturbance. According to different definitions of performance, it can be classified into stable robustness and performance robustness. The fixed controller designed with the robustness of the closed-loop system as the target is called the robust controller.
Robust Stability is robust stability (Professional words)

The. NET Framework is evaluated as "robust platform for enterprise and Web Application Security (a reliable platform for enterprise and Web Application Security )".

Today I tried a new string usage, as shown below:

Sizeof ("A") = 2

Sizeof ("AB") = 3

Sizeof ("ABC") = 4

 

"ABCD" [2] = C
-----------------------------------------------------------------------

// Variable Parameter exercises

# Include <stdio. h>

# Include <stdarg. h>

 

Int myprint (char * FMT ,...)

{

Va_list argptr;

Int rn;

 

Va_start (argptr, FMT );
// Note that the data type of argptr is char *

Rn = vfprintf (stderr, FMT, argptr );

Va_end (argptr );

 

Return rn;

}

 

Int main (void)

{

Int I = 10, j = 20;

Char s [] = "ABC ";

 

Myprint ("% d, % d, % s/n", I, j, S );

}
