In any programming language we go with writing bunch of ifs else ifs and else statement if there are bunch of conditions in a scenario.
if(case1){
}
else if(case1){
}
else(case1){
}
In these situations we can go with a switch statement also.
switch (country)
{
case India:
break;
case USA:
break;
case China:
break;
default:
}
But, what if we have only two conditions for a scenario like shown below.
We have an integer variable.
int val = 10;
I just want to check whether it is an even one or an odd one. To check this we can go for if statements also as shown below.
if(val %2 == 0){
// Even number
}
else{
// Odd number
}
Instead of above style, We can use conditional operator to make it a single line as shown below.
BOOL even = (val %2 == 0) ? YES : NO
If the condition is success, even will have YES value. If not a NO value.
In these cases, this operator is simple and handy and readable. Isn't it?
Hope this post is useful. Feel free to comment in case of any queries.
