Question

Please help me with those 2 question problem, please help, thanks!!

Code (Please use visual studio):

#include <stdio.h>
#include <string.h>

#pragma warning(disable : 4996) // compiler directive for Visual Studio only

// Read before you start:
// You are given a partially complete program. Your job is to complete the functions in order for this program to work successfully.
// All instructions are given above the required functions, please read them and follow them carefully.
// You shoud not modify the function return types or parameters.
// You can assume that all inputs are valid. Ex: If prompted for an integer, the user will input an integer.

// Global Macro Values. They are used to define the size of 2D array of characters
#define NUM_STRINGS 4
#define STRING_LENGTH 50

// Forward Declarations
void initializeStrings(char[NUM_STRINGS][STRING_LENGTH]);
void printStrings(char[NUM_STRINGS][STRING_LENGTH]);
void reverseStrings(char strings[NUM_STRINGS][STRING_LENGTH]);
void encryptStrings(char[NUM_STRINGS][STRING_LENGTH], int);
void decryptStrings(char[NUM_STRINGS][STRING_LENGTH], int);
int splitAndPrintSentences(char s[NUM_STRINGS*STRING_LENGTH]);
void inputMatrix(int matrixA[3][3]);
void determinant(int matrixA[3][3]);

// Problem 6: splitAndPrintSentences
// Split s[] into individual sentences and store them in str[][].
// Read s[] character by character and copy into str[][], such that sentence 1 is in str[0][], sentence 2 is in str[1][] and so on.
// Print the char array str[][], so that you will print the separated sentences. Finally return the number of sentences in 'count'
// Dont forget to initialize str[][] with nulls.
// Hint: Sentences are separated by full-stop.

int splitAndPrintSentences(char s[NUM_STRINGS*STRING_LENGTH])
{
   char str[NUM_STRINGS][STRING_LENGTH];
   int count = 0;
   // enter code below

   return count;

}

// Problem 7: inputMatrix
// Ask the user for each element of the 3X3 matrix and store the elements in "matrixA[][]"
// Display the matrix in the following form:
// matrixA =
// 1 2 3
// 4 5 6
// 7 8 9
// The user may input any inetgers for matrix elements, not necessarily same as example above.
void inputMatrix(int matrixA[3][3])

Here is the code for the functions.

I have added the main function for testing.

#include <stdio.h>

#include <string.h>

#pragma warning(disable : 4996) // compiler directive for Visual Studio only

// Read before you start:

// You are given a partially complete program. Your job is to complete the functions in order for this program to work successfully.

// All instructions are given above the required functions, please read them and follow them carefully.

// You shoud not modify the function return types or parameters.

// You can assume that all inputs are valid. Ex: If prompted for an integer, the user will input an integer.

// Global Macro Values. They are used to define the size of 2D array of characters

#define NUM_STRINGS 4

#define STRING_LENGTH 50

// Forward Declarations

void initializeStrings(char[NUM_STRINGS][STRING_LENGTH]);

void printStrings(char[NUM_STRINGS][STRING_LENGTH]);

void reverseStrings(char strings[NUM_STRINGS][STRING_LENGTH]);

void encryptStrings(char[NUM_STRINGS][STRING_LENGTH], int);

void decryptStrings(char[NUM_STRINGS][STRING_LENGTH], int);

int splitAndPrintSentences(char s[NUM_STRINGS * STRING_LENGTH]);

void inputMatrix(int matrixA[3][3]);

void determinant(int matrixA[3][3]);

// Problem 6: splitAndPrintSentences

// Split s[] into individual sentences and store them in str[][].

// Read s[] character by character and copy into str[][], such that sentence 1 is in str[0][], sentence 2 is in str[1][] and so on.

// Print the char array str[][], so that you will print the separated sentences. Finally return the number of sentences in 'count'

// Dont forget to initialize str[][] with nulls.

// Hint: Sentences are separated by full-stop.

int splitAndPrintSentences(char s[NUM_STRINGS * STRING_LENGTH])

{

    char str[NUM_STRINGS][STRING_LENGTH];

    int count = 0;

    // enter code below

    int j = 0;

    for (int i = 0; i <= strlen(s); ++i)

    {

        // end of sentence

        if (s[i] == '.' || s[i] == '\0')

        {

            str[count][j] = '\0';

            count++;

            j = 0;

        }

        // normal character

        else

        {

            str[count][j] = s[i];

            j++;

        }

    }

    return count;

}

// Problem 7: inputMatrix

// Ask the user for each element of the 3X3 matrix and store the elements in "matrixA[][]"

// Display the matrix in the following form:

// matrixA =

// 1 2 3

// 4 5 6

// 7 8 9

// The user may input any inetgers for matrix elements, not necessarily same as example above.

void inputMatrix(int matrixA[3][3])

{

    // reading input from user

    for (int i = 0; i < 3; ++i)

    {

        for (int j = 0; j < 3; ++j)

        {

            printf("Enter element (%d, %d):\t", i + 1, j + 1);

            scanf("%d", &matrixA[i][j]);

        }

    }

    // printing output in the correct format

    printf("matrixA = \n");

    for (int i = 0; i < 3; ++i)

    {

        for (int j = 0; j < 3; ++j)

        {

            printf("%d ", matrixA[i][j]);

        }

        printf("\n");

    }

}

int main()

{

    // test function for inputMatrix fiunction

    int matrixA[3][3];

    inputMatrix(matrixA);

    // test function for splitAndPrintSentences fiunction

    char s[NUM_STRINGS * STRING_LENGTH] = "Hi.Hello.Hi there.How are you";

    printf("Number of statements:\t%d", splitAndPrintSentences(s));

    return 0;

}
