Using C programing Write an appropriate declaration for each

Using C programing

Write an appropriate declaration for each of the following situations involving pointers Declare a function that accepts an argument which is a pointer to an integer quantity and returns a character. Declare a function that accepts an argument which is an integer a and returns a character. A C program contains the following declaration. static char color [6] (\"red\", \"green\", \"blue white black\' \"yellow\"); What is the meaning of color? What is the meaning of (color 2)? What is the value of *color? What is the value of *(color 2)? How do color [5] and *(color 5) differ?

Solution

1) a

char func(int *a)

{
return \'z\'; // any char
}

b)

char func(int *a[])

{
return \'z\';
}

2)

a)

color is pointer to array

i.e. color[0] will hold red

color[1] will hold green

b)

(color+2) will hold address of blue

c)

*color will give red

d)

*(color+2) will give blue

e)

*(color+5) will give yellow

color[5] will five yellow

both are same
