Question

New instructions for this assignment. They want it to accept all types of uppercase/lowercase. and q should be to quit. Want the use of switch case. Very very basic c program

Create an algorithm for a menu based program that uses a switch-case statement to include the following options:

a) Print your name.

b) Print your tutorial time.

c)  Prompt the user to enter a positive number between 1-50, read the entered input, and display all numbers from 0 up to the number entered (the display should print five numbers per line).

E.g: if the user enters 5, the program will display 0 1 2 3 4 5.

q) Quit

The user should be able to continuously enter and execute options until they enter the 'q' character to quit. The algorithm should be able to accept the upper- and lower-case versions of all character input options and should be able to deal with invalid options being input for all input (including the number required for part c).

Answer 1

C Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
//variables
char name[50], choice;
//getting the name
printf("Enter your name: ");
scanf("%s",name);
//getting time
time_t current_time = time(NULL);
char* c_time_string;
c_time_string = ctime(&current_time);

//looping until user hits q
while(1){
printf("Choose an option\n");
printf("a) Print your name\n");
printf("b) Print your tutorial time\n");
printf("c) Enter a number between 1-50\n");
printf("q) Quit\n");
scanf("%s", &choice);//getting choice
switch(choice){
case 'a':
case 'A':
//printing name
printf("Your name is %s\n",name);
break;
case 'b':
case 'B':
//printing time
printf("Your tutorial time is %s\n",c_time_string);
break;
case 'c':
case 'C':
//getting and printing the numbers
printf("Enter the number: ");
int num;
scanf("%d", &num);
//checking for valid input
if(num<1 || num>50){
printf("Invalid Input\n");
}else{
for(int i=0;i<=num;i++){
printf("%d ", i);
}
}
printf("\n");
break;
case 'q':
case 'Q':
//quiting
return 0;
default:
printf("Invalid Input\n"); //in case of invalid input

}
}
return 0;
}
