怎么编写代码把用"*"分隔的12345和67890和34567分别取出来并打印 |
|
|
|
|
|
char * str="12345*67890*34567"
char* str1=memcpy(str,str1,5); char* str2=memcpy(str+6,str2,5); char* str3=memcpy(str+12,str3,5); |
|
|

可以用strstr找出个各子窜的位置在用楼上的memcpy就搞定了。
|
|
|
|
楼上的代码。。。空间都没
sscanf(str,"%d*%d*%d",a,b,c); 或自己一个个字符读取，用*和0做分界符 |
|
|
|
#include <string.h>
#include <stdio.h> char string[] = "12345*67890*34567"; char seps[] = "*"; char *token; void main( void ) { printf( "%s\n\nTokens:\n", string ); /* Establish string and get the first token: */ token = strtok( string, seps ); while( token != NULL ) { /* While there are tokens in "string" */ printf( " %s\n", token ); /* Get next token: */ token = strtok( NULL, seps ); } } |
|
|
|
用STL
|
|
|
|
char * str="12345*67890*34567"
while(1) { while(*str!='*'){ printf("%c",*str++); } if(*str=='\0') break; str++; } 大致辞 |
|
|
|
#include <stdio.h>
void main() { printf("\n123456789034567\n"); } |
|
|
|
char * str="12345*67890*34567"
while(1) { while(*str!='*'){ printf("%c",*str++); if(*str=='\0') break; } str++; } 上面那个有点错，大概的内容如此吧！不是很清楚，望谅解！！！ |
|
|
|
在“str++;"加上
printf("\n");更好 |
|
|
|
while(*s)
{ if( *s!='*' ) putchar(*s++); else if(*s=='*') printf("\n"); else break; } |
|

同意 larryvc() 的做法!
|
|
|
|
char str[] = "12345*67890*34567";
char sep[] = "*"; char *pdest = NULL; pdest = strstr(str, sep); while ( pdest != NULL ) { *pdest = '\n'; pdest = strstr(str, sep); } printf("%s", str); |
|
|
|
用CString 最好
|
|
|
|
while( *s ){
if( *s!='*' ) putchar( *s ); ++s; } |
|
|
|
boxban(master-dreamer) 的是标准c的做法！

完全可用版
#include "stdio.h" #include "string.h" main() { char xyz[] = "1234*567*8910"; char *p; p = xyz; while(*p) { if(*p != '*') { putchar(*p); } else { printf("\n"); } p++; } printf("\n"); } |

奇怪，为什么没人用strtok，很好用的函数啊，强烈推荐。
|
|
|
|
#include <stdlib.h>
#include <string.h> #include <iostream.h> void main( void ) { char str[] = "12345*67890*34567"; char *buffer = new char[strlen(str)]; long tmp; int len=0; tmp = atol(str);; _ltoa(tmp, buffer, 10); while(1) { cout<<buffer<<endl; len += strlen(buffer); if(len == strlen(str)) break; len++; tmp = atoi(str+len); _itoa(tmp, buffer, 10); } delete buffer; } |

qiuzhang:的程序就是啊
不必要用其他的函数 |
|
|
|
strtok吧，通用性强些
