The goto statement is an unconditional transfer statement that is used in the following format:Goto statement label;Where the label is a valid identifier, with a ":" (colon) that appears somewhere inside the function, after the goto statement is

When considering what C + + is doing, Java is doing a good deed, simplifying the issue of how parameters are passed. In C + +, there is no method in C + +, which should be called "function" or "member function", and the parameters and method calls

If you need to execute different established operations for different situations, but you still need to follow the conventional execution process, the task cannot be completed. In this case, you need to introduce the concept of process redirection,

If you need to execute different established operations for different situations, but you still need to follow the conventional execution process, the task cannot be completed. In this case, you need to introduce the concept of process redirection,

Return statementterminates the execution of a function and returns control of the calling function (or control of the operating system if you transfer control from the main function). Resumes execution immediately after the call in the calling

Example 1: # Include # include int main (void) {char STR [256]; scanf ("% s", STR); If (strlen (STR) Example 2: # Include int main (void) {int I = 0; while (1) {I ++; printf ("% d \ n", I ); if (I = 10) goto AAA;} AAA: printf ("OK! \ N ")

Previously seen effect xxx and other books, there will always be this one: avoid using goto statements The reason is very simple, you a piece of code will jump here, a jump there, jump to the dizzy, like in the maze It seems to make sense, but in

Example 1: #include　 #include　 int　main(void) { 　　char　str[256]; 　　scanf("%s",　str); 　　if　(strlen(str)　 　　　　goto　Label1; 　　}　else　{ 　　　　goto　Label2; 　　} 　　Label1: 　　　　printf("\n输入内容没有超过10个字符"); 　　　　goto　Label3; 　　Label2:

If for different situations, need to perform different established operations, if or according to the normal execution process, is unable to complete the task, this time, it is necessary to introduce the concept of process jump, using the process

The C language provides a variety of looping statements that can form a variety of different forms of loop structure: The loop is formed by the Goto statement and the IF statement; Use the while statement; Use the Do-while statement;

I. Break   1. break statement format: break;   2. break statement function:      A. In A switch statement, break is part of its syntax in this province. The break statement terminates the execution of the subsequent statement and exits the switch

JAVA supports three jump statements:Break, continue, and return. These statements transfer control to other parts of the program. Next we will discuss each statement. Note: apart from the jump statements discussed here,Java also supports another

C # programs execute on a line-by-line, top-down, with no missing code. In order for the program to execute according to the process designed by the developer, it is necessary to make the process of condition judgment, loop and jump, which need to
