我的C程序一直在崩溃

我有这个小程序,我需要用字母表替换我输入的任何字符串,所以a = 01,b = 02,n = 14,7 = 07 ...例如,如果我输入ab36c作为输出我应该得到01 02 03 06 03

当我在另一台计算机上编译这一切时,一切正常,现在当我在我的电脑程序崩溃时运行它,我仍然可以输入我的字符串,但当我按Enter键获得结果(输出)时,它显示program.exe已停止工作.什么错了？

    int i, j, garums;

    gets(text);

    garums=strlen(text);

    for (i=0;i<=garums;i++){ 
        for (j=0; j<=36;j++)
            if( text[i]==simboli[j]){
                strcat(s2,morze[j]);
                strcat(s2," ");

            break;
            }
    }

    puts(s2);

    scanf("%c");
}

你做strcat(s2,morze[j]);但s2从未初始化,因此它最有可能指向无效的内存,因此崩溃.

编辑:

...而且scanf("%c")因为你没有提供参数而崩溃.你需要:

char c ;
scanf("%c", &c) ;

EDIT2:

这是没有使用simboli和morze数组的版本:

char *outp = s2 ;
for (i = 0; i <= garums; i++)
{
  char c = text[i] ;    
  if (c >= 'a' && c <= 'z')
    outp += sprintf(outp, "%02d ", c - 'a' + 1) ;
  else if (c >= '0' && c <= '9')
    outp += sprintf(outp, "%02d ", c - '0') ;
}

EDIT3

总结一下:

替换:char *s2 ;用char s2[200];和替换scanf("%c") ;用scanf("%c", &c) ;
