jarptica [38.1K]

Using the knowledge in computational language in Java it is possible to write a code that function as CountingMinutes:

<h3>Writing the code in Java:</h3>

function CountingMinutes(str) {

     // code goes here  

     // Declare variables for calculating difference in minutes

     // variables in JavaScript are declared with "let" keyword

     /* Build regelar expression which will match the pattern of "12houttime-12hourtime"

        and extract time or hours in numbers from it */

     let extractedTimeStringArray = str.match(/(\d+)\:(\d+)(\w+)-(\d+)\:(\d+)(\w+)/);

     // extractedTimeStringArray array will be like- ["1:00pm-11:00am", "1", "00", "pm", "11", "00", "am", index: 0, input: "1:00pm-11:00am", groups: undefined]    for str = "1:00pm-11:00am"

     // console.log('object', time)

     

     // Extract array value at 1st index for getting first time's hours (ie time before hyphen like 1:00pm in 1:00pm-11:00am )  (like 11 from 11:32am) and convert them to minutes by multiplying by 60

     let mintsOfFirstTimeFromHours = extractedTimeStringArray[1] * 60;

     // Extract array value at 2nd index for getting first time's minutes like 32 from 11:32am

     let mintsOfFirstTimeFromMints = extractedTimeStringArray[2];

     // Extract array value at 4th index for getting second time's hours (ie time after hyphen like 11:00am in 1:00pm-11:00am ) and convert them to minutes by multiplying by 60

     let mintsOfSecondTimeFromHours = extractedTimeStringArray[4] * 60;

     // Extract array value at 5th index for getting second time's minutes like 32 from 11:32am

     let mintsOfSecondTimeFromMints = extractedTimeStringArray[5];

     // if second time's 12 hour time is in pm

     if (extractedTimeStringArray[6] === "pm") {

       // Add 12 * 60 = 720 minutes for 12 hrs

         mintsOfSecondTimeFromHours += 720;

     }

     // if first time's 12 hour time is in pm

     if (extractedTimeStringArray[3] === "pm") {

        // Add 12 * 60 = 720 minutes for 12 hrs to first time

       mintsOfFirstTimeFromHours += 720;

        // Add 12 * 60 *2 = 1440 minutes for 24 hrs to second time

       mintsOfSecondTimeFromHours += 1440;

     }

     // Calculate output minutes difference between two times separated by hyphen

    str = (mintsOfSecondTimeFromHours - mintsOfFirstTimeFromHours) + (mintsOfSecondTimeFromMints - mintsOfFirstTimeFromMints);

     // return calculated minutes difference

     return str;

   }

   // keep this function call here

   // call the function and console log the result

   console.log(CountingMinutes("1:00pm-11:00am"));

   // output in console will be-  1320

Can you answer this question?
patriot [66]

Answer:

To do this you'll need to use malloc to assign memory to the pointers used.  You'll also need to use free to unassign that memory at the end of the program using the free.  Both of these are in stdlib.h.

#include <stdlib.h>

#include <stdio.h>

#define SIZE_X 3

#define SIZE_Y 4

int main(void){

       int **matrix, i, j;

       // allocate the memory

       matrix = (int**)malloc(SIZE_X * sizeof(int*));

       for(i = 0; i < SIZE_X; i++){

               matrix[i] = (int *)malloc(SIZE_Y * sizeof(int));

       }

       // assign the values

       for(i = 0; i < SIZE_X; i++){

               for(j = 0; j < SIZE_Y; j++){

                       matrix[i][j] = SIZE_Y * i + j + 1;

               }

       }

       // print it out

       for(i = 0; i < SIZE_X; i++){

               for(j = 0; j < SIZE_X; j++){

                       printf("%d, %d:  %d\n", i, j, matrix[i][j]);

               }

       }

       // free the memory

       for(i = 0; i < SIZE_X; i++){

               free(matrix[i]);

       }

       free(matrix);

       return 0;

}
