Solution

To scan the variables 'a' and 'b' in C, you would use the following scanf() statement:

scanf("%f %lf", &a, &b);

Here is the step by step explanation:

  1. %f is the format specifier for a float in C. This is used to scan the variable 'a'.

  2. %lf is the format specifier for a double in C. This is used to scan the variable 'b'.

  3. &a and &b are the addresses of the variables 'a' and 'b'. The scanf() function needs the addresses of the variables in order to change their values.

  4. The variables are separated by a space in the scanf() function, which means that the input should also be separated by a space.
