C++ :: Display Maximum Value In Two Dimensional Array Of Integers
Feb 3, 2014
How will you code a program that displays the maximum value in a two dimensional array of integers. the program will ask the user to input the 4x5 array?
i know how to code it. but i dont know what to do to find the maximum value. :( how to find the maximum?
display the 3rd element of a two dimensional array of integers named T of size 2x5?? i don't know how to start because i'm just advance studying with array
I am new to programming all together but i have been writing a program in c++ and im coming up against an issue with my array.
#include<iostream> #include<iomanip> #include<string> using namespace int main () { int a ; int b ; char answer ('Y') ;
[Code] ....
I am trying to get the program to increase say year one by 1 when the condition is met i have tried
if ( a >= 70 && a <= 100 && b == 1) {grade [0][0] = 0 + 1;}
and
for (grade[0][0] = 0 ; a >= 70 && a <= 100 && b == 1 ; grade [0][0]++) {grade [0][0]= 0 + 1 ;}
Now all that i want is that the array will take the information from int a and int b and then add 1 to the appropriate part of the array . I have tried putting it in deferent places but its not working for ether. the program will run but it will not add to the array.
//Introductory20.cpp - displays the contents of a two-dimensional array, column by column and row by row
#include <iostream> using namespace std; int main() { int nums[2][4] = {{17, 24, 86, 35}, {23, 36, 10, 12}};
[Code] .....
I need modifying a program that should display the contents of the two- dimensional array, column by column and also row by row. I need to complete the program using a WHILE statement in the outer loops and a FOR statement in the nested loops.
1.Create one 2-dimensional array. The array will consist of numbers from 1 to 10. And will also contain the number in words. Display the values of the 2-dimensional array.
Sample output: 1 - One 2 - Two 3 - Three
Paste the program code here:
2.Create a program that will accept two integer numbers. These integer numbers will be the limit of the multiplication table. Store the values in a two dimensional array.
Sample output: Enter x: 3 Enter y: 2 123 246
Paste the program code here:
3. Determine the output produced by the following program segment.
int ROWS = 3; int COLS = 4; int [ ] [ ] val = {{8,16,9, 52},{3,15,27,6},{14,25,2,10}}; for (int i=0; i < ROWS; i++) { for (int j= 0; j<COLS; j++) System.out.print (val [i][j] + " " ); System.out.println (); }
I am working on a number of utility functions for two dimensional arrays of integers, or matrices. However I am having a problem with segmentation faults, most likely due to errors in using malloc in functions like copyMatrix.
Code: matrix_utils.h~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ //This function checks if two matrices are equal int isEqual(int **A, int **B, int n);
//This function returns one row of a matrix int * getRow(int **A, int i, int n);
//This function returns one column of a matrix int * getCol(int **A, int j, int n);
How can I concatenate two 2-dimensional int arrays into one larger 3-dimensional array. This question is also valid for the 3-dimensional vectors. I know the command for the one dimensional vector as:
In pseudocode and in C code, declare two 1-dimensional parallel arrays of Integers to store the age and weight of a group of people that will hold the information of up to 10 people. Use a For loop to iterate through the array and input the values. This is the code i have, but my array is showing up as 11 and not 10?
I had a hard question in my C++ final exam and I'm trying to solve it for the last 3 days. I haven't succeded yet! Here is the question: You have a one-dimensional array A[20]={1,2,3,4,...,20} and B[5][4] you have to assign the A array's elements to the B array but there is an order which is: B[5][4] = { { 12, 9, 11, 10 }, { 14, 7, 13, 8 }, { 16, 5, 15, 6 }, { 18, 3, 17, 4 }, { 20, 1, 19, 2 } } and there is a restriction: you can only use ONE for statement, nothing else!
#include <iostream> #include <iomanip> using namespace std; int main(){ int A[20] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 }; // define A array's elements. int B[5][4] = { 0 }, k = 1; // define B array and k counter.

I can't narrow the statements to one,This program works perfectly but it shouldn't be that long, we need ONLY ONE FOR statement, not two!
I have a 3D array that contains 200 strings. I'm trying to copy all these strings into a 2D array. How can this be done? This is what I have so far but it isn't working correctly.
Code: for(int i = 0; i < row; i++) { for (int j = 0; j < col; j++) { dest[i][j] = source[0][i][j]; } }
The finished product would be with 100 rows, 2 columns.
Any way to determine the highest value of an array I created with random numbers. I am confused because the array needs to be initialized in the main, but populated in a function. I was able to populate it using a pointer variable and my results came out good for the initial array values and elements.
In order to figure out the max, I think I would need the results of the populated array. How do I do this when the populated array is stored in a pointer variable? Would I need to create a pointer to the first pointer I created? I tried creating another pointer to the initial array and printing that, but my results were not good.
I was given some practice problems in my programming class, to prepare for the final and I don't quite understand what this one is asking for exactly:
Write the remainder of the program to find the maximum value for the middle row of the array data. Print the max after finding it. Your code should work for any 2D array of ints with three rows and four columns, so don't hard-code your program to these specific values.
i have tried like that int arr[1000000] to initialize but it crashed my programm.but if i do int arr[100000] it works fine..why is that and what is the maximum range of integer array initialization??
Here's the code that returns maximum sum of a subsequence from a given array. This is according to "Programming Pearls" by Jon Bentley. I have come up with an example for which this program won't work. And here's that example:
{ -10, 11, 10, -10, 2, 3, -6, 1 }
Max subsequence sum above is 21. 2nd and 3rd elements.
But the program returns 16. It sums 2nd through 6th elements and returns. Why would the writer explain something with such depth, only to give a program that doesn't work in all instances?
int MaxSum(int lo, int hi, int* arr) { if (lo > hi) { return 0; } if (lo == hi)
Write a program using user-defined function which accepts an integer array and its size as arguments and assign the elements into a two dimensional array of integers in the following format: If the array is 1,2,3,4,5,6, the resultant 2D array is
I want to make a program that asks the user for a message and then print out a large graphic of that message. For example, if the user types "he" I want to print out
H..................H EEEEEEEEE H..................H E H..................H E H..................H E HHHHHHHHHH EEEEEEEEE H..................H E H..................H E H..................H E H..................H EEEEEEEEE
(treat the periods as spaces. I only put them there because it wouldn't separate the H's correctly.)
I will loop this to continue until the user types quit.
1. How would I set this up to store the user input characters into an array?
2. How would I print out the stored data in the shape of the word?
