A(n)___________is represented in memory as an array of characters with a null terminator.
“C-string” is a series of characters that are stored in successive memory locations and it is terminated by a null character.
Explanation of Solution
C-string:
C-string is a series of characters that are stored in successive memory locations and it is terminated by a null character.
The ASCII code for the null character is 0, but in C++ and many programming languages it is represented by ‘\0’.
- In a program, c-strings can be used in three forms. They are:
- Programmer-defined arrays of character
- Hard-coded string literals
- Pointers to character
- C++ language also provides some library functions to work with C-strings. Some of them are:
- “strlen” function – This function helps to find the length of the string.
- “strcat” function – By using this function, two or more than two strings can be concatenated.
- “strcpy” function – This function is used to copy the string from one variable to another variable.
- “strcmp” function – This function helps to compare strings.
- In order to use C-string library functions, the header file “#include<cstring>” must be used.

- (Electrical eng.) Write a program that specifies three one-dimensional arrays named current, resistance, and volts. Each array should be capable of holding 10 elements. Using a for loop, input values for the current and resistance arrays. The entries in the volts array should be the product of the corresponding values in the current and resistance arrays (sovolts[i]=current[i]resistance[i]). After all the data has been entered, display the following output, with the appropriate value under each column heading: CurrentResistance Voltsarrow_forward(Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().arrow_forward(Numerical) Write and test a function that returns the position of the largest and smallest values in an array of double-precision numbers.arrow_forward
- (List maintenance) The following letters are stored in an alphabet array: B, J, K, M, S, and Z. Write and test a function named adlet(), which accepts the alphabet array and a new letter as arguments, and then inserts the new letter in the correct alphabetical order in the array.arrow_forward(Statistics) Write a program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main().arrow_forwardAn array that uses two indices is referred to as a(n) ________________array.arrow_forward

- Fill-in-the-Blank The __________ operator can be used to work with the variable a pointer points to.arrow_forwardCreate the following code in C Create a program that has an array for which the user determines the maximum size. The array’s elements will be of some user defined type (struct) that you will make up. This array will be stored in disjoint dynamic memory. The program must have some type of menu. You will pick your own theme for the program. No previous themes can be used. Be sure to utilize error checking and be sure you free of all memory used on the heap.arrow_forwardYou are provided a 2 dimensional array is created by the statement: 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 What value is accessed by the following statements: num[1][7] = _________________ num[0][5] = __________________ num[1][4]= ___________________ num[0][9]= _____________________ num[1][0]=_____________________ Extra Credit: What is a common property of the values in the area? You are implementing a Stack of chars The following statements are issued: push (‘a’) push (‘b’) push (‘c’) push (‘d’) pop() push(‘z’) pop() push(‘e’) push(‘f’) push (‘g’) pop() Display a representation of the stack at the end of the operations above from top to bottom. You must label the top and bottom. You have a queue of numbers and you issue the following instructions: (10 pts.) add(33) add(57) add(75) add(12) remove() remove() add(101) add(99) remove() add(67) remove() add(33) remove() List…arrow_forward
