为什么以下程序的输出每次都不同（随机值）？

Question

Can we assign the string value to the int variable? what conversion is happening at line int a="aa"; I am running this C program and the value is printing different for each program execution.

 int main() 
{
   int a="aa";
   printf("%d",++a);
   return 0;
 }

In C, the string literal "aa" is a char * (in C++ a const char * ) to a read-only memory location of the string "aa" . You are converting this pointer to an integer, ie the memory address to a number. Depending on the platform you are using, this memory address may change every time your program runs.
