An array is a collective name given to a group of similar variables. In this program we will accept two 2-D array (2 by 2 Matrix) as input from the user. This program will then perform addition of two 2 by 2 matrix. It will then display the result after adding two matrix. Here is the program for matrix addition. If you found this article useful, do post a comment. #include #include void main(){ int arr1[10][10], arr2[10][10]; int arr3[][3]={ {0,0,0}, {0,0,0}, {0,0,0} }; int i, j; clrscr(); printf(“Enter 3×3 array 1:\n”); for(i=0;i<3;i++){ for(j=0;j<3;j++){ printf(“Enter element %d x %d:”,i,j); scanf(“%d”,&arr1[i][j]); }...

The below mentioned program copies the content of one array name ‘source’ into another array named ‘dest’ in the reverse order. In case you have any queries related to the below mentioned program, please don’t hesitate to comment on this post. Your comments are always welcomed. #include #include void main(){ int source[100], dest[100],i,j,no; clrscr(); printf(“Enter the number of elements: “); scanf(“%d”,&no); for(i=0;i<no;i++){ printf(“Enter Source Array Element%d :”,i+1); scanf(“%d”,&source[i]); } for(i=0,j=no-1;i<no;i++,j–){ dest[j]=source[i]; } printf(“Destination array:\n”); for(i=0;i<no;i++){ printf(“%d\t”,dest[i]); } getch(); } Output: Enter the number of elements: 10 Enter Source Array Element1 :1 Enter Source Array Element2 :2 Enter Source Array Element3...
