2D array

Matrix definition

 

// This is called 2metrix in programing world

//calculating memory consumption rule is:- (rows*columns)*datatypesize = total memory consumption;
      _      _
eg: | 2    6|
      |5     5|   =>  (rows*columns)*datatypesize  => (2*2)*4 => 16 bytes is memory consumption
      -        - 
 1D array deceleration is:- int[] number = new int[size];
2D array  deceleration is:- int[][] number = new int[rows][columns];
 
 eg: //Example of 2darray and calculating sum
 int a[][], i, j,sum=0;
printf("Enetr element of matrix:  :");
 
for(i=0;i<2;i++){
for(j=0; j<3;j++){
sacnf("%d", &a[i][j]);
}
}
 
printf("Martix is\n");
for(i=0;i<2;i++){
for(j=0; j<3;j++){
printf("%d\t",  a[i][j]);
sum = sum + a[i][j];
}
printf("\n");
} 
printf("\n Sum = %d",sum);
}
 
 //transpose of matrix

prisma using in project idx 13.3

Okay, let's troubleshoot why you might be unable to use the Prisma schema in your Project IDX workspace. Here's a breakdown of common reasons and how to fix them: 1. Prisma is not installed Problem:  Prisma might not be installed in your IDX environment. Solution:  You'll need to add it to your  .idx/dev.nix  file, like this: nix { pkgs, ... }: { # ... other configurations packages = [ # ... other packages pkgs.nodePackages.prisma ]; # ... rest of your configuration } lua (auto) Once you add this line and  rebuild the environment  by clicking the popup message, IDX will install  prisma  and make it available in your workspace. 2. The Prisma CLI is not accessible Problem:  After installation, you might need to explicitly call the Prisma CLI using its full path or use  npx . Solution:  When running Prisma commands in your terminal (in IDX), use  npx prisma  (e.g.,  npx prisma migrate dev ) or ...
