> 1. The following function calls supposedly write a single new-line character, but some are incorrect. Identify which calls don't work and explain why.
|
|
|
|
b. `printf("%c", "\n");` - This is invalid because the double quotes make `\n` a string, but it's being displayed with the `%c`formatting specifier.
|
|
c. `printf(%s, '\n');` - This is invalid because it's trying to display a `char` using the string formatting specifier.
|
|
e. `printf('\n');` - `printf`'s first argument should be a string, not a `char`.
|
|
h. `putchar("\n");` - `putchar`'s first argument should be a `char`, not a string.
|
|
i. `puts('\n');` - `puts`'s first argument should be a string, not a `char`.
|
|
j. `puts("\n");` - `puts` will write a newline after writing a string, so this will write two newlines. |
