How do you get the output12345 1234 123 12 1?
printf ("12345 1234 123 12 1\n"); ... or, did you mean to do it with loops ? ... int i, j; for (i=5; i>0; i--) { for (j=1; j<=i; j++) printf ("%d", j); printf (" "); } printf ("\n");

Find sum of elements row wise and columm wise?
#include<stdio.h> #include<conio.h> void main() { int i,a[3][3]={1,2,3,4,5,6,7,8,9},j,s=0,m,n; clrscr(); /*for(i=0;i<3;i++) { for(j=0;j<3;j++) { printf("\na[%d][%d]= ",i,j); scanf("%d",&a[i][j]); } }*/ for(i=0;i<3;i++) { for(j=0;j<3;j++) { printf("%d",a[i][j]); } printf("\n\n"); } for(i=0;i<3;i++) { for(j=0;j<3;j++) s=s+a[i][j]; printf("\n Sum of %d`th row=%d",i+1,s); s=0; } { int i,j,s=0; for(j=0;j<3;j++) { for(i=0;i<3;i++) s=s+a[i][j]; printf("\n\t\t Sum of %d`th column=%d",j+1,s); s=0 ; } } getch(); }
How old is James if he is twice as old as David was when James was as old as David is now?
He is 4/3 of David's age. The original version of this question has a sum of their ages, which would allow you to get a numerical answer. (e.g. sum of 56, ages are 32 and 24). If James is 8, David is 6 - when James was 6, David was 4 If James is 12, David is 9 - when James was 9, David was 6 J = 2 [ D - (J-D)] J = 2 (2D-J) J = 4D - 2J 3J = 4D J = 4/3 D
Sum of two matrices in c program?
#include<stdio.h> #include<conio.h> main() { int a[4][4],b[4][4],c[4][4],i,j; printf("enter the elements of matrix a"); for(i=0;i<=3;i++) for(j=0;j<=3;j++) scanf("%d",&a[i][j]); printf("the first matris is"); for(i=0;i<=3;i++) { printf("\n"); for(j=0;j<=3;j++) printf("%d",a[i][j]); } printf("Enter the elements of second matrix"); for(i=0;i<=3;i++) for(j=0;j<=3;j++) scanf("%d",&b[i][j]); printf("the second matrix is"); for(i=0;i<=3;i++) { printf("\n"); for(j=0;j<=3;j++) printf("%d",b[i][j]); } for(i=0;i<=4;i++) for(j=0;j<=4;j++) c[i][j]=a[i][j] + b[i][j]; printf("the addition of matrix is"); for(i=0;i<=3;i++) { for(j=0;j<=3;j++) printf("%d\t",c[i][j]); printf("\n"); } getch(); }
