Program to print an 2D array

[Sarfaraj Khan]

Hi friend,

I am getting troubled while coding C program for 2D array. I have one program to print one dimensional array but not able to code program for two dimensional array. I have one program code for 2D array but it's not displaying the desired output. If you have C program to print an 2D array, then please share same program with me. Your help would be greatly appreciable.

Hi,
Please refer following program, which will show you how to print the 2D array:

#include<stdio.h>
#include<conio.h>
voizd main()
{
int a[50][50],k,row,column;
printf("enter number of rows & columns of 2D array :");
scanf("%d%d",&row,&column);
for(int iz=0;iz<row;iz++)
{
for(int q=0;q<column;q++)
{
scanf("%d",&a[iz][q]);
}
}
for(iz=0;iz<row;iz++)
{
k=0;
for(q=0;q<column;q++)
{
k=k+a[iz][q];
}
printf("%d\n",k);
}
getch();
}

To print the 2D array, for this you need to use the nested loop. I think nested for loop is perfect for this situation. In which you need to use two for loops. Assign first first for loop to print the columns for the 2D array. While the assign second for loop to print the rows of the 2D array. See following:

for(irr=0;ir<row;ir++)
{
kr=0;
for(qr=0;qr<column;qr++)
{
kr=kr+ar[ir][qr];
}
printf("%d\n",kr);
}

Hello friend,

Printing two dimensional array is quit different from printing one dimensional array. Two loops are required to print the values of two dimensional array. One is for rows and another for to print column:

strArray[][]=// put value for 2D array
for(int iv=0;iv<strArray.length;iv++) {
for(int jv=0;jv<strArray[iv].length;jv++) {
System.out.print(strArray[i][j]);
}
System.out.println();
}

I recommend you use following program code in your program for to print the 2D array:

int AT[3][3];

for(ibx=0;ibx<3;ibx++)

{
for(jbx=0;jbx<3;jbx++)
{

printf(" %d" AT[ibx][jbx]);
}
printf("\n");
}

Thanks friend for your help!!
I have tried to run the above mentioned code for to print the two dimensional array. There are some miner syntax error in the program code. I corrected that error. All program codes was very easy to understand. It also helped me to understand the use of nested loop in C program. I think it's not very difficult to print the 2D array as it seems. I appreciating you help.
