1. CSCE 206 Lab Structured Programming in C
Spring 2019
DEBUG

2. Ideas on how to debug
Go line by line IN ORDER from the start of the program and think what each line DOES
Put printf() after each statement where you modify something
You can start from the ones that you doubt
Also to calculate partial results if you have large formulas
Calculate by hand the partial results to compare
Create other inputs to find corner cases
Create another set of inputs and calculate by hand what the total should be
Check that it also produces a good output

3. Debugging code #include <stdio.h> int main(void) { int a, b;
float c, d, total;
printf("Enter 4 numbers:");
scanf("%d %d %f %f",&a, &b, &c, &d);
total = (((c*d)-a)/b)+(c*d)-(b*a/b);
printf(”The total is:%f\n", total);
return 0; }
