vaskoz / for_blocks.go
Created April 12, 2014 17:20
4 different Go For loops, but 2 don't use blocks the same was as the other 2. "for_blocks_fmt.go" is the gofmt version, but it breaks the code by its formatting because it changes the CForLoopNoPrePost example so that it doesn't compile if you add the newline as the original.
package main
// There are 4 FOR examples below, but they differ in how they require
// blocks to start.
import "fmt"
// CANNOT start block on next line
func CForLoop() {
sum := 0
