1、重庆理工大学C语言期末试题改错编程题void fun(char *a,char *b,char *c) int i,j; char ch; i=0; j=strlen(b)-1;/*found*/ while (ij)这里大小写符号错了 ch=bi;bi=bj;bj=ch; i+; j-; while (*a|*b)/*found*/ if (*a) *c=*a;c+;a+;这里他的错误时if大写了 if (*b) *c=*b;c+;b+; *c=0; #include /*found*/float fun ( float r)这里要有r不能用x否则是错的/*found*/ return 3.
