Is it necessary to write “{}” in if statement, if here is only two lines in it?

//Example if(x<y){ y=88 y=9} //or if(x<y) y=88 y=9

Have you tried the comma operator? It works in some cases, like the one you have here. Helpful when you want to save some braced lines. Eg : #include <iostream> using namespace std; int main() { int x=1, y=2; if(x<y) y=88,y=9; cout<<y; }

in 1st code if( x<y ) { y = 88; y = 9; } if condition is true block of code executed and in 2nd code if( x<y ) y = 88; y = 9; if condition is true y = 88 executed otherwise rest of flow execution ie y = 9 executed !

@Sofia S. Tkachenko There isn't any limit to the use of the comma operator. It can be used simultaneously for 3, 4 or more lines. Its just that the operator fails when you use some type of functions like system(), exit(), etc..

Yes, you must if you're having multiple lines of code.
