# Format specifiers in C

Format specifiers define the type of data to be printed or interpolated in
standard output. You need to use format specifiers whenever you are
[printing values in C](./Printing_values_in_C.md).

For example:

```c
int age = 37
printf("My age is %i", age)
```

| Specifier | Usage   |
| --------- | ------- |
| `%c`      | char    |
| `%s`      | string  |
| `%n`      | nothing |
| `%i`      | integer |
| `%f`      | float   |
