looping via a goto
Conditionals and Loops example from a Well House Consultants training course
More on Conditionals and Loops [link]
Source code: fresh.c Module: C203
#include <stdio.h>
/* A program that loops via a goto statement The goto statement, where you can jump around a program to change the flow of your logic, is generally accepted to be a bad thing to use. You end up with spaghetti code that's hard to follow, and hard to debug. For the sake of completeness in our examples, here's a program that shows the use of goto */ main () { int siblings = 17; float gifttotal = 100000.0; float each; looper: each = gifttotal / siblings; printf("With %d sibles each gets %.2f\n",siblings, each) ; if (siblings > 1) { siblings = siblings - 1; goto looper; } } /* Sample output: munchkin:ac grahamellis$ gcc -o fresh fresh.c munchkin:ac grahamellis$ ./fresh With 17 sibles each gets 5882.35 With 16 sibles each gets 6250.00 With 15 sibles each gets 6666.67 With 14 sibles each gets 7142.86 With 13 sibles each gets 7692.31 With 12 sibles each gets 8333.33 With 11 sibles each gets 9090.91 With 10 sibles each gets 10000.00 With 9 sibles each gets 11111.11 With 8 sibles each gets 12500.00 With 7 sibles each gets 14285.71 With 6 sibles each gets 16666.67 With 5 sibles each gets 20000.00 With 4 sibles each gets 25000.00 With 3 sibles each gets 33333.33 With 2 sibles each gets 50000.00 With 1 sibles each gets 100000.00 munchkin:ac grahamellis$ */ Learn about this subject
