1.字元陣列賦值：char c1[20] = "women";

2。將數轉為字元賦值給陣列

#include <stdio.h>
#include <cstdlib>
#include <stdlib.h>
int main()
{
    char c1[20] = "women";
    int num=10,num1=101;
    char str[100];
    itoa(num,str,16);//將num轉換化16進位制賦值給str 
    printf("%s\n",str);
    itoa(num1,str,2);//將num轉換化2進位制賦值給str 
 

    printf("%s\n",str);
    char s[10];
    sprintf(s, "%d", 123); //產生"123"，賦值給陣列 
    printf("%s\n",s);
    sprintf(s, "%8d%8d", 123, 4567); //產生：" 123 4567" ，賦值給陣列
    printf("%s\n",s);
    sprintf(s, "%-8d%8d", 123, 4567); //產生："123 4567"
    printf("%s\n",s);
    sprintf(s, "%8x", 4567); //小寫16 進位制，寬度佔8 個位置，右對齊
 

    printf("%s\n",s);
    sprintf(s, "%-8X", 4568); //大寫16 進位制，寬度佔8 個位置，左對齊
    printf("%s\n",s);
    sprintf(s, "%08X", 4567); //產生："000011D7"
    printf("%s\n",s);
    sprintf(s, "%08x", 4567); //產生："000011D7"
    printf("%s\n",s);
    sprintf(s,"%7.2f",23.35);
    printf("%s\n",s);
      sprintf(s,"%.2f",23.35);
    printf(
 
"%s\n",s);
    getchar();
}
