Pointers

< >
Example from 1 languages: C
int *ptr;
Example from 1 languages: Go
package main import "fmt" func main() { i, j := 42, 2701 p := &i // point to i fmt.Println(*p) // read i through the pointer *p = 21 // set i through the pointer fmt.Println(i) // see the new value of i p = &j // point to j *p = *p / 37 // divide j through the pointer fmt.Println(j) // see the new value of j }
Example from 1 languages: C#
// Pointers supported only under certain conditions. // Get 16 bytes of memory from the process's unmanaged memory IntPtr pointer = System.Runtime.InteropServices.Marshal.AllocHGlobal(16);
Example from 1 languages: Felix
var x = 1; &x <- 2;
Example from 1 languages: Jule
let ptr: *int = nil
Example from 1 languages: Speedie
|| i = 0 || p = &i *p = 1 if (i == 1) "success"
Example from 1 languages: Fortran 90
