PRVI PROGRAM
V datoteko main.cpp napišemo program:
#include <stdio.h>
char s[] = "GeeksforGeeks";
int main()
{
int a = 2000, b =17;
printf("%s %d \n", s, a+b);
}
Compiling & running
da program skompajliramo zaženemo ukaz:
gcc main.cpp -o main
zaženemo program main
./main
Cpp to assembly
gcc -S main.cpp
in dobimo strojno kodo:
