See more:

Write a program using two-dimensional arrays that computes the sum of data in rows of the 3x3 (three by three) array variable n[3][3].
Sample input/output dialogue:

Enter numbers: 5 9 8 3 8 2 4 3 9
Output:
5   9   8 = 12
3   8   2 = 13
4   3   9 = 16

How to add computes

C

#include<stdio.h>
 int main()
    { 
    /* 2D array declaration*/
     int disp[3][3];
     /*Counter variables for the loop*/ 
    int i, j; 
    for(i=0; i<3; i++)
     { 
        for(j=0;j<3;j++)
         { 
printf("Enter value for disp[%d][%d]:", i, j); 
       scanf("%d", &disp[i][j]);
             } 
        } 
    //Displaying array elements
     printf("Two Dimensional array elements:\n");
     for(i=0; i<3; i++)
     { 
        for(j=0;j<3;j++)
         {
             printf("%d ", disp[i][j]); 
            if(j==2)
                {
                 printf("\n");
                 } 
            } 
        } 
    return 0; 
    }

Try

C

#include <stdio.h>
  
void input (int disp[][3]);
void show (int disp[][3]);

int main()
{
  int disp[3][3]; // the uninitialised matrix
  input(disp); // gather user inputs
  show(disp); // display the matrix and the row sums
  return 0;
}

void input ( int disp[][3] )
{
  for(int i=0; i<3; i++)
  {
    for(int j=0;j<3;j++)
    {
      printf("Enter value for disp[%d][%d]:", i, j);
      scanf("%d", &disp[i][j]);
    }
  }
}
void show( int disp[][3])
{

  printf("Two Dimensional array elements:\n");
  for(int i=0; i<3; i++)
  {
    int sum = 0;
    for(int j=0;j<3;j++)
    {
      sum += disp[i][j];
      printf("%d ", disp[i][j]);
    }
    printf(" = %d\n", sum);
  }
}

You have written most of the code correctly. Only sum is missing.

Will modify your code by adding 2 new lines and modify two lines. That's it... Problem will be solved.

All changes were in bold for your reference

C

//In the begining declare one more variable called "sum"
int i, j, sum;


//Taken your existing code and added one new line (sum = 0) and modified your printf

//Displaying array elements
     printf("Two Dimensional array elements:\n");
     for(i=0; i<3; i++)
     { 
        sum = 0;
        for(j=0;j<3;j++)
         {
             printf("%d ", disp[i][j]); 
             sum += disp[i][j];
             // Removed that (j == 2) condition
         }

          printf("= %d\n", sum);
        } 
    return 0; 
    }

}
return 0;
}
