Section 3.7 Summary

Activity 3.7.

Take a moment and think about the following:

What was your main take-away from today’s class?
What was the most confusing in today’s class?

Here is what we have learned:

printf() is used to display a message to the screen. Example:
```
printf("This will be displayed on the screen!");
```
🔗
🔗
\n starts a new line. Example:
```
printf("Hello!\nMy name is Petra!");
```
🔗
🔗
Quotation marks need to be "escaped", as in: \", \'. Example:
```
printf("She said: \"Today it\'s Monday!\" ");
```
🔗
🔗

Loops are used to repeat instructions multiple times. Example:

int i;
for (i=0; i<3; i++) {  
    printf("Hello! ");
    printf("Hi!\n");
}

Comments are important throughout your code. Comments can be included in your code by enclosing them in /* ... */ or by using //. Example:

int main(void) {
    int i; /* This is a comment. */
    /* This is also a comment. */
    /* A comment
       can go over
       multiple lines.
    */
    for (i=0; i<3; i++) {  
        printf("Hello! "); // This comment ignores the remainder of the line.
        printf("Hi!\n");
    }
}
