Hello and welcome to CS50!
Welcome to the first coding section of CS50! This week we will be learning programming fundamentals in C. C is a powerful language that is used in many different applications, from operating systems to video games. It is a great language to learn because it is relatively low-level, meaning that you have a lot of control over how your code runs. This week we will be learning about variables, conditionals, loops, and more!

Common Patterns for the Problem Set
do while loops
int input;
do
{
input = get_int("Enter an integer: ");
}
while (input < 0)
printf
printf prints a formatted string to the terminal:
// print text
printf("hi\nhi")
// print the value of variables
int num = 2
printf("the value of this number is %i", num)
// can also do for strings, doubles, floats, etc. (%s, %d, %f, etc.)
