The toupper function will change a character argument from lowercase to uppercase.
<h3>What is toupper function?</h3>
The toupper() function exists utilized to convert the lowercase alphabet to uppercase. i.e. If the character passed exists in a lowercase alphabet then the toupper() function converts a lowercase alphabet to an uppercase alphabet. It exists represented in the ctype. h header file. The toupper() function in C++ converts a provided character to uppercase. It exists defined in the ctype header file.
The toupper() function transforms the lowercase letter c to the corresponding uppercase letter. Both functions return the transformed character. If the character c does not include a corresponding lowercase or uppercase character, the functions return c unchanged.
Hence, The toupper function will change a character argument from lowercase to uppercase.

Physical memory is how much RAM you have installed on your computer.
Answer:
2.6 seconds
Explanation:
We first start by calculating the speed up
The formula is given as:
n/1+(n-1)F
We have n = 3 which is the number of processors
F = 20% = percentage of algorithm
When we put values into the formula
3/1+(3-1)0.20
= 3/1+2*0.20
= 3/1+0.4
= 3/1.4
Speed up = 2.14
From here we calculate the expected time
T/speedups
= 5.6/2.14
= 2.6
Therefore the expected time is 2.6 seconds
