to typecast integer to char* 不,你不能。 void *不包含类型信息,因此无法确定它实际指向的类型。 is the << operator overloaded for each and every type? 是 is there a way to achieve it through just one generic overloaded function? 这个问题没有意义..你只想要一个函数,还是想要一个重载函数? 相...

3. Since library code is connected at compile time, the final executable has no dependencies on the library at run timei.e. no additional run-time loading costs, it means that you don’t need to carry along a copy of the library that is being used and you have everything under your ...

Int myworker(void*)Then we need to typecast myworker as (void* (*)(void*))&myworker Now if the worker function has more than one arguments, then we need to create a struct and need to typecast that to void*. For example, worker function has one int and one char as arguments....
Hence, we have to typecast one of the integer operands to float, as shown below −ExampleTake a look at this example −Open Compiler #include <stdio.h> int main(){ int x = 10, y = 4; float z = (float)x/y; printf("%f", z); return 0; } Output...
