num=num/10;
}
return ct;
}

int main()
{
int num=12345;
printf("length of %d is %d\n",num,integer_length(num));

return 0;
}

main.c } 1 #include <stdio.h> 2 int integer_length(int num) 3- { 4 int ct=0; 5 while(num! =) 6 { 7 ct++; 8 num num/10; 9 10 return ct; 11 } 12 13 int main() 14- { 15 int num=12345; 16 print ("length of %d is %d\n", num, integer_length(num)); 17 18 return 0; 19} 20 input length of 12345 is 5 ... Program finished with exit code o
