I take the following message of error. How I can correct him? error: `array' undeclared (first use in this function) error: (Each undeclared identifier is reported only once error: for each function it appears in.) Code: void display(int b[9][9]) { int i,j; for(i = 0; i <9; i++) { if(i%3==0)printf("+---------+---------+---------+\n"); printf("%d",i+1); for(j = 0; j <9; j++) { if(j%3==0) printf("| "); printf("%d ", array[i][j]); } printf("\n"); } printf("\n"); if(i%3==0) printf("+---------+---------+---------+\n"); }
