C Programming - Control Instructions - Discussion

Option D is correct. Since there are some if statements which do not have any else part and they cannot be converted into ?: So 3 conditions are fulfilled but first condition is not fulfilled.

@Akash is right, because this might be the case when we need to use a loop under if else statement, but we can't use looping with conditional operator. Only that is why first option is not correct.

Can we multiple else statements?

If so which else statement will be executed in case failure of if statement?

Option 3. Multiple statements in an if block are allowed - is also correct, because we can execute multiple statements against true value of if (condition) by placing the statements within { and }.

So all the options are correct.

Guys 1st option is wrong because we can not use any loop in that operator but we can use any looping statements in if else.

#include<stdio.h>
int main()
{
int i,a=5;
if(a==5)
{
a==5?for(i=0;i<5;i++){printf("namastey\n");}:printf("error");

}
}

This code will give an error "expression syntax ".

@Gautam && @Madhu:

Yes gautam you are absolutely right I tried this code and it works, here the code is:

#include<stdio.h>
int main()
{
int x=10;
/*if(x>5)
{
printf("this is integer number:\n");
printf("this number is greater than 5\n");
printf("\n");
}
else if(x==5)
{
printf("this is an integer number:\n");
printf("the number is equal to 5:\n");
printf("\n");
}
else
{
printf("number is smaller than 5\n");
printf("\n");
}*/
x>5?(printf("this is integer number:\n"),printf("this number is greater then5\n")):(x==5?(printf("this is an integer number:\n"),
printf("the number is equl to 5:\n")):printf("number is smaller than 5\n"));
return(0);
}
Output:
This is integer number:
This number is greater than 5.

//So again we are at the same place where we started anyone please explain it very clearly.

#include<stdio.h>
int main()
{
int a = 10, b,c;
a >=5 ? (b=100,c=12): (b=200,c=15);
printf("%d %d\n", b,c);
return 0;
}

We may write multiple statements in this way in ?: operator. Then why option 1 is wrong? Please explain.

@Madhu.

You are right for this case but many case like (return X) in if condition so ?: is not allowed if condition only.

Friends here only only if - else can be replaced by ternary operator but not more than one it is wrong so there he specified more than one if-else.

Finally we can find only one solution using conditional statement that is to be assigned to its L-value, not more than one result as using if-else,

Ex. if(i==2)
{a=100; b=400; c=300;}
else
{a=0;b=0;c=1}

You can't write any conditional statement.
