In C++03, the return type of a function template cannot be generalized if the return type relies on those of the template arguments. Here is an example, mul(T a, T b) is a function template that calculates the product of a and b. Arguments a and b are of an arbitrary type T, whi...
Exit function in C is defined in stdlib.h and used to terminate processes. There are two types of exit status (EXIT_SUCCESS and EXIT_FAILURE)
Status Getstack(SqStack &S, SElemType e){ // 改&e 为：e, 这就允许你用常数调用。main(){ SqStack S; // 改&S 为 S if(S.top==S.base) exit(0); // 改掉 返回 return ERROR; 例如用 exit(0); 因为 void 函数体内 不能用 return 语句。
`main' is not `int'原文翻译是：警告：main函数的返回类型不是int C语言用的turboc编译器里警告还是能正常运行的，但是不安全，你的函数头是不是写了 int main(){ } 1。可以改成void main(){ }或者不写void，在vc++编译器里必须加返回类型 2。int main(){ 加个return 0;/* 系统正常退...
@文心快码a.c: in function 'main': a.c:7:5: warning: ignoring return value of 'scanf' 文心快码 1. 解释warning信息的含义 这个warning信息表示编译器在编译你的C程序时,发现你调用了scanf函数,但没有检查其返回值。scanf函数在读取输入时,会返回一个值,指示成功读取的输入项的数量。忽略这个返回值可能...
