Solution

To scan the variables 'a' and 'b' in your code, 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. So, it is used to take the input for the variable 'a' which is of float type.

  2. %lf is the format specifier for a double in C. So, it is used to take the input for the variable 'b' which is of double type.

  3. The & symbol is used before the variable names 'a' and 'b' to provide the address of the variables, so that scanf() can modify their values.

  4. The two format specifiers are separated by a space, which means that the input values should also be separated by a space when you enter them.
