Language in C 面试题与答案
Question: If the result of an _expression has to be stored to one of two variables, depending on a condition, can we use conditional operators as shown below?
Answer: No! The above statement is invalid. We cannot use the conditional operators in this fashion. The conditional operators like most operators, yields a value, and we cannot assign the value of an _expression to a value. However, we can use conditional operators as shown in following code snippet.main( ) { int i, j, k, l ; i = 5 ; j = 10 ; k = 12, l = 1 ; * ( ( i < 10 ) ? &j : &k ) = l * 2 + 14 ; printf ( "i = %d j = %d k = %d l = %d", i, j, k, l ) ; } The output of the above program would be as given below: i = 5 j = 16 k = 12 l = 1 |
