The C Programming Language says: An integer constant like1234is anint. Alongconstant is written with a terminall(ell) orL, as in123456789L; an integer constant too big to fit into anintwill also be taken as along. Unsigned constants are written with a terminaluorU, and the suffixulorULi...
If the value of the integer constant is too big to fit in any of the types allowed by suffix/base combination,it does not have suffixeswb,WB,uwb, orUWB(since C23)and the compiler supports extended integer types (such as__int128), the constant may be given the extended integer type; ...
在整形常量上使用了不正确的后缀"f"f是浮点常量不想用double而是float时用的 整数的话至少最后加个小数点也行啊 : 1.f 1.0f
数学表达式不能全部直接应用到C语言：2n改成2*n
For example, in C programming, the following line of code creates a constant integer variable and assigns it a value of 10:。 const int num = 10;。 In this case, the constant initializer is the value 10, which is used to initialize the variable 'num'. Since the variable is marked as...
