打印char数组的一部分

printf

#include <stdio.h>

int main(void) {
  char s[] = "something";
  int start = 3;
  int len = 5;

  printf("%.*sn", len, s + start);

  return 0;
}

Char *p ="Something";

char *temp=p;

temp=temp+3;

while(*temp!='g')

printf("%c",*temp++);

char* strSth = "something"; 
std::string strPart; 
strPart.assign(strSth+3,strSth+8);
std::cout << strPart;

#include <stdio.h>

int main()
{
        char a[1024] = "abcdefghijklmnopqrstuvwxyz";
        printf("Characters 0 through 2 of a[]: %.3sn", a);
        printf("Characters 10 through 15 of a[]: %.6sn", &a[10]);
        return 0;
}

Characters 0 through 2 of a[]: abc
Characters 10 through 15 of a[]: klmnop
