Exercises 3
1. For each of the following, give examples of data that will be read correctly and
examples of data that will cause the program to crash. Assume the declaration
int i, j; double x, y;);
(a) scanf("%d %d", &i, &j);
(b) scanf("%lf %lf", &x, &y);
(c) scanf("%d %lf %d", &i, &x, &j);
2. For 1(c), state what will be stored in i, x, and j for each of the following sets
of data:
(a) 14 11 52
(b) -7 2.3 52
(c) 0 6.1 7.0
(d) 1.0 8 -1
3. Write a program that requests a user to enter a weight in kilograms, and converts it
