Golang Process Control if statement

1. If Else statement

Basic syntax

Single condition judgment if condition {    //do something}//multi-condition judgment if condition {} else if condition {    //do something} else {//do    so Mething}

If single condition followed by a statement and then made conditional judgment

If statement;condition{    //do something}//single condition, without the basic judgment of the statement package Mainimport ("FMT") func main () {nu: = 1if nu%2 = = 0 {fmt. Println ("The number is even")} else{fmt. Println ("The number is odd")}}//single condition, with statement of Judgment package Mainimport ("FMT") func main () {   if nu: = +; Nu% 2 = = 0 {//with an assignment statement After doing the judging   fmt. Println ("The number is even")   } else{   fmt. Println ("The number is odd")   }}

Note: It is not very build justice to do this because logic looks complicated, but it can reduce the amount of code

If multi-criteria followed by a statement and then made conditional judgment

Multi-condition, without statement of Judgment package Mainimport ("FMT") func main () {num: = 34if num <= 50{fmt. Println ("number is not then")} else if num >= && num <= 100{fmt. Println ("The number is between And1")} else{fmt. Println ("The number is greater than 100")}}//multi-criteria, with Statement of Judgment package Mainimport ("FMT") func main () {//num: = 34if num: = 78;num &L T;= 50{fmt. Println ("number is not then")} else if num >= && num <= 100{fmt. Println ("The number is between And1")} else{fmt. Println ("The number is greater than 100")}}
