15, there are 17 people in a circle (numbered 1-17), starting from the 1th number 1, 2, 3 count, where 3 people quit,//the next person from 1 began to count .... Until the last person. What is the number of the person's original position, please? #include <stdio.h>int main () {int P[18]={0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17};int i=1,j=1,k=1,m=17;do {if (P[i]) {if (j++>=3)//reported 1 number {p[i]=0;j=1;m--;} Elsek=i;if (m<=1) break; if (i>=17)//If it is the last element, the next element is p[1]i=1;else//or p[i+1]i++;} while (1);//loop continuously until it is necessary to stop printf ("%d\n", k); return 0;}

16, there is a line of text, asked to delete one of the characters. Both this line of text and the characters to be deleted are entered by the keyboard */* #include <stdio.h>int main () {char Str1[100],str2[100];char ch;int i=0,k=0;printf ("\nplease Input a phase\n "), while ((Str1[i]=getchar ()) = ' \ n ')//assigns a value to the str1 array i++;str1[i]= ' + ';//At the end of the string, add a ' + ' as the end sign printf (" \ Ndelete? "); scanf ("%1s", &ch); for (i=0;str1[i]!= '; i++ ') {if (str1[i]!=ch) str2[i-k]=str1[i];elsek=k+1;} Str2[i-k]= ';p rintf ("\n%s\n", str2); return 0;} *//* #include <stdio.h>int main () {char A[10];char b;int i,j;printf ("Please enter chars:"), gets (a);p rintf ("please Enter Delete char: "); B=getchar (); for (i=0;i<10;i++) {if (a[i]==b) for (j=i;j<10;j++) {a[j]=a[j+1];}} printf ("%s\n", a); return 0;} */
