It can be done with 7 LED segments.
More LEDs will be needed if a regular rectangular array is required, but many of these will never light and could be omitted to save money but then it would not be regular.
The smallest standard regular rectangular array sold is 5 by 7 or 35 total LEDs, but this will display all alphanumeric characters and even then some LEDs will be unused unless other things are displayed too.
Just guessing the smallest regular array is probably 3 by 5 or 15 total LEDs, but at most 13 of these LEDs would be used by the digits the other 2 LEDs could be omitted to save money. Such an array could be wired to be driven as a 7 segment display using a few ordinary diodes to light the 6 shared LEDs as part of multiple "segments".

Find smallest no in matrix in c plus plus?
Store the first value in the matrix, then compare every value in the matrix with the stored value, replacing the stored value if the current value is smaller. For instance, the following snippet will locate the smallest int value in a 3x4 matrix named A: int smallest=A[0][0]; for(int x=0; x<3; ++x ) { for(int y=0; y<4; ++y ) { if(A[x][y]<smallest ) { smallest=A[x][y]; } } }
