Solution for Exercise 7-15

ex0715

#include <stdio.h>

int main()
{
    float fav;

    printf("What is your favorite number: ");
    scanf("%f",&fav);
    printf("%f is my favorite number, too!\n",fav);
    return(0);
}

Notes

* Only three changes are required to convert fav into a float variable: The declaration on Line 5 and the %f for scanf() in Line 8 and printf() in Line 9.

* If you type a whole number, the scanf() function reads it as a floating point value. That's okay for program input, but remember that when you write your code you should specify the decimal when typing a float value.
