Now this one's a tad bit tricky, but you can definitely do it!

Instructions:

1. Input five integers in one line, with each integer separated by a space.
2. Add the 1st and 2nd integers together, store the sum inside a variable.
3. Add the 3rd and 4th integers together, store the sum inside a variable.
4. Multiply the two sums with each other and raise the product to the power of the 5th integer
5. Print out the result.

Input

A line containing five integers separated by a space.

1·2·3·4·5

Output

A line containing an integer.

We've tried adding together integers, now how about strings?

Instructions:

1. Input two strings in one line, separated by a space.
2. Concatenate the two strings and print out the result.

Input

A line containing two strings separated by a space.

hello·world

Output

A line containing the concatenated string with no spaces.

Question No.1 Implement this program by using User-defined functions and Structures.

Write a program that reads students’ names followed by their test scores. The program should output each student’s name followed by the test scores and the relevant grade. It should also find and print the highest test score and the name of the students having the highest test score. Student data should be stored in a struct variable of type studentType, which has four components: studentFName and studentLName of type string, testScore of type int (testScore is between 0 and 100), and grade of type char. Suppose that the class has 20 students. Use an array of 20 components of type studentType. Your program must contain at least the following functions:

1. A function to read the students’ data into the array.

2. A function to assign the relevant grade to each student.

3. A function to find the highest test score.

4. A function to print the names of the students having the highest test score.

CAT-6 twisted pair cable is a commonly used computer networks cable that provides a frequency bandwidth of up to 250 MHz. It is suitable for most varieties of Ethernet over twisted pair up to 1000 BASE-T (Gigabit Ethernet). Determine whether a signal-to-noise ratio (SNR) of 20 dB is adequate to transmit 0.9 Gbps on this cable?
