#include int main() { int x = 4, y, z; y = --x; z = x--; printf("%d %d %d", x, y, z); } Output: 2 3 3 Can anyone explain this? ... but maybe the it doesn't. Making main an int and having the program return 0 is a change that should be made, of course. - Brian. Commented Oct 8, 2010 at 14:25
Here the expression a**b*a + *b uses pointer in C/C++ concept. Here a**b*a + *b means 5*(value of pointer b that is 5)*5 +(value at pointer b which is 5 again). So the result is 130. 2. What will be the output of following program?
All valid C programs must contain the main() function. The code execution begins from the start of the main() function. The printf() is a library function to send formatted output to the screen. The function prints the string inside quotations. To use printf() in our program, we need to include stdio.h header file using the #include

#include The preprocessor assumes, it is a standard library header and looks in the system folders first where the compiler has been installed. If instead a programmer defines a function by himself and place the .h file in the current working directory, he would use (note the double quotes) #include "stdio.h"
