array

Question

an array can be passed in a function in C through

a)call by value only    b)call by reference only  c)both by call by value and call by reference d) none

Answer 1

Always call by reference only

Answer 2

An array is passed in a function by call by reference method. The name of the array acts as the reference for the array.

e.g. traverse(a,10);// function call by passing array name as reference

An array element can be  passed as call by value.

e.g. traverse(a[4],10);// function call by passing  individual element using call by value

So, option (b) is correct.
