Is there a way to shorten the if else statements with switch?

I need to find a way to shorten my if-else statements with switch. The if-else statements are really long and they look really unprofessional and I hope there is a way to shorten them into a couple of lines instead of the mess of multiple lines as I have it now.

I tried to implement a switch block but it didn't go correctly and the way I wanted it to go.

int numbers(int tal[]) {
int choice,a;
printf("\nWrite a specific number: ");
scanf("%d", &choice);
int b = 0;
for(a = 0 ;a < MAX ;a++){
    if(tal[a]== choice){
        b = 1;
        printf("\nExists in the sequence on this location: ");
        if(a <= 9)
        printf(" Row 1 och column %d\n",a +1);
        else if (a > 9 &&a <= 19)
        printf(" Row 2 och column %d\n", (a +1) - 10);
        else if (a > 19 &&a <= 29)
        printf(" Row 3 och column %d\n", (a +1) - 20);
        else if (a > 29 &&a <= 39)
        printf(" Row 4 och column %d\n", (a +1) - 30);
        else if (a > 39 &&a <= 49)
        printf(" Row 5 och column %d\n", (a +1) - 40);
        else if (a > 49 &&a <= 59)
        printf(" Row 6 och column %d\n", (a +1) - 50);
        else if (a > 59 &&a <= 69)
        printf(" Row 7 och column %d\n", (a +1) - 60);
        else if (a > 69 &&a <= 79)
        printf(" Row 8 och column %d\n", (a +1) - 70);
        else if (a > 79 &&a <= 89)
        printf(" Row 9 och column %d\n", (a +1) - 80);
        else if (a > 89 &&a <= 99)
        printf(" Row 10 och column %d\n", (a +1) - 90);
        break;
    }
}
if (b == 0)
    printf("\n%d It does not exists in the sequence", choice);
}

I got it working, and I changed all the if-else statements to this one; edit: nvm the column answer I get is incorrect.

int choice,a,row,col;
printf("\nWrite a specific number: ");
scanf("%d", &choice);
int b = 0;
for(a = 0 ;a < MAX ;a++){
    if(tal[a]== choice){
        b = 1;
        printf("\nExists in the sequence on this location: ");
        if(a <= 9)
       col = a % 10 + 1;
       row = a / 10 + 1;
       printf("Row %d och column %d\n", row, col);
        break;
    }
}
if (b == 0)
    printf("\n%d It does not exists in the sequence", choice);

You can make it look a bit better by:

  • Properly indenting it
  • Omitting redundant checks with >

like that:

if(a <= 9)
    printf(" Row 1 och column %d\n",a +1);
else if (a <= 19)
    printf(" Row 2 och column %d\n", (a +1) - 10);
else if (a <= 29)
    printf(" Row 3 och column %d\n", (a +1) - 20);
...

But in this case you can completely avoid the if-block by calculating the values, for example like that:

col = a % 10 + 1;
row = a / 10 + 1;

print("Row %d och column %d\n", row, col);
