I'm new to multidimensional arrays and I just don't understand how to write into them.. help?
Code:int main(void) { int nums[3][5]; int i,j; printf("Enter 3 sets of 5 double numbers: "); for(i=0; i < 3; i++) { for(j=0; j<5; j++) scanf("%d", nums[i][j]); } for(i=0, j; i<3,j<5;i++,j++) printf("%ld",nums[i][j]); return 0; }
> scanf("%d", nums[i][j]);
If this doesn't complain, then bump up the compiler warning level - you forgot the &
Eg.
Code:$ gcc -W -Wall -ansi -pedantic -O2 bar.c bar.c: In function `main': bar.c:11: warning: format argument is not a pointer (arg 2) bar.c:15: warning: left-hand operand of comma expression has no effect bar.c:16: warning: long int format, int arg (arg 2)
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
oh wow such a small mistake to me forever .. thanks a lot now works
Code:int main(void) { int nums[3][5]; int i,j; printf("Enter 3 sets of 5 double numbers: "); for(i=0; i < 3; i++) { for(j=0; j<5; j++) scanf("%d", &nums[i][j]); } for(i=0; i < 3; i++) { for(j=0; j < 5; j++) printf("%2d\n",nums[i][j]); } return 0; }
