Chapter 3 ■ Programs with Sequence Logic
When executed,
• The printf statement will ask for your name.
• gets will wait for you to type your name. When typed, the name will be
stored in the variable name.
• printf will then print a greeting using your name.
Your computer screen will look as follows (assuming Birdie is typed as the name):
Hi, what's your name? Birdie
Delighted to meet you, Birdie
3.5 Examples
We now write programs to solve a few problems. You should try solving the problems before
looking at the solutions. In the sample runs, the underlined items are typed by the user;
everything else is printed by the computer.
3.5.1 Problem 1 - Average
Write a program to request three integers and print their average to one decimal place. The
program should work as follows:
Enter 3 integers: 23 7 10
Their average is 13.3
A solution is shown as Program P3.4.
Program P3.4
//request 3 integers; print their average
#include <stdio.h>
int main() {
int a, b, c;
double average;
printf("Enter 3 integers: ");
scanf("%d %d %d", &a, &b, &c);
average = (a + b + c) / 3.0;
printf("\nTheir average is %3.1f\n", average);
}
