So finden Sie die erste und letzte Ziffer einer Ganzzahl in C.
#include <stdio.h>
int main()
{
int n, sum=0, firstDigit, lastDigit;
printf("Enter number = ");
scanf("%d", &n);
// Find last digit of a number
lastDigit = n % 10;
//Find the first digit by dividing n by 10 until n greater then 10
while(n >= 10)
{
n = n / 10;
}
firstDigit = n;
printf("first digit = %d and last digit = %d\n\n", firstDigit,lastDigit);
return 0;
}
