说明：主要找你的填空题第一道题的题干，然后后面的答案都是相对应一套一套的，如：假如你的填空题第一道题的题干和这里的第1套是一样的（有些提干是一模一样的，如第1和25，33、36和39，27和49，请继续看第二个found），那你所有题的答案都是相对应的第1套（用红色字体标注了）假如你的题干和这里的第18套题是一样的，那么你所有题的答案都是相对应的第18套题（蓝色字体标注了）。其他类推。一、填空题1/*found*/ t = _1_;（同25一样）/*found*/ t *= (-1.0)*x/_2_;（1）x （2）n (3)fabs(t)2/*found*/ switch(_1_)(1)n%10 (2)break (3)break3/*found*/if(t%2=_1_)(1)0 (2)10*x (3)n/104/*found*/ rmax=aij; c= _1_ ; (1) j (2)0 (3)i+5/*found*/void fun(char (*ss) _1_, int k)(1) M (2)N (3)06/*found*/void fun(int (*t)_1_ )(1)N (2)tij (3)tji7/*found*/void fun(int (*a)N, int _1_)(1) k (2)N (3)aki8/*found*/while(t=_1_)(1) 999 (2)t/10 (3)x9/*found*/ _1_;(1) sum=0 (2)tii (3)110/*found*/_1_ fun(char ch)(1) char (2)ch=9 (3)011/*found*/s=0; i=_1_;(1) 0 (2)i+ (3)2.*i12/*found*/while (!feof(_1_)(1) (fp) (2)= (3)fp13/*found*/for(i=0; i _1_ ; i+)(1) N (2)substr (3)014/*found*/for(p=1; pb)?(bc?b :(ac?c:_1_):(ac)?_2_:(bc)?c:_3_);(1) a (2)a (3)b16/*found*/ if (ch=a)_1_(ch=len) strcpy(_1_);(1) t,s (2)si (3)020/*found*/_1_ fun(struct student *a)(1) struct student * (2)a-scorei (3)a21/*found*/ max = min = _1_;(1) ai (2)aj (3)aj22/*found*/void fun(int _1_ , int n)(1) tN (2)i=0;in (3)s23/*found*/void fun(int _1_, int n)(1) *a (2)2 (3)i+124/*found*/ f = 1.0+_1_;(1) x (2)n (3)t25/*found*/ t = _1_;（同第1题一样）/*found*/ for (i=_2_; isno (2)-name (3)&t27/*found*/k=_1_;(同第49题一样)/*found*/ t=_2_;(1) 1 (2)2*i (3) (-1)28/*found*/s=_1_;(1) 0 (2)n (3)(t*t)29/*found*/ ch=tolower(_1_);(1) *s (2)1 (3)kn30/*found*/ _1_ t;(1) struct student (2)n-1(3),31/*found*/ if (_1_= 0) (1) ai%2 (2)aj (3) j32/*found*/ t=*n % _1_;(1) 10 (2)0 (3)x33/*found*/for(i=0; i _1_ ; i+)（同第36和第39一样）/*found*/ if(len= _2_) (1) N (2)k (3)ssi34/*found*/ _1_ ; flag=1;(1) n+ (2)0 (3)s+35/*found*/ tj=_1_; j+;(1) si (2) k (3)036/*found*/ for(i=0; i (3)(2*i+1)39/*found*/ for (i=0; i_1_; i+)/*found*/ai = an-1-_2_;（同第33和第36一样）(1) n/2 (2)i (3)an-i-140/*found*/ b = _1_;(1) a (2) (3)scorei41/*found*/ for (_1_; ji; j+)(1) j=2 (2)i (3)j42/*found*/ i=_1_;(1) 1 (2)s (3)i*1043/*found*/_1_ fun(struct student a)(1) struct student (2)(3)a.scorei44/*found*/ p=(n%2=0)?n/2:n/2+_1_;(1) 1 (2)i (3)ap+i45/*found*/ if (ai%2=_1_)(1) 1 (2)j+ (3)j46/*found*/n=_1_;(1) 0 (2)x (3)t+47/*found*/ *(t+n)= _1_ ; n+; (1) *s (2)s+ (3)n48/*found*/#define OK(i, t, n) (_1_%t=0) & (i/tn)(1) i (2)t+ (3)count49/*found*/k= _1_ ;(同第27题一样)/*found*/if(strlen(psk) strlen(_2_) ) k=j;(1) i (2)psj (3) tp50/*found*/ for (j=ai*2; j=n; j+=_1_)(1)ai (2)ai (3)0二、改错题1.(1)for(i=1;i=y;i+) (2)t=t%1000;2.(1)if(t=0) (2) *zero=count;3.(1)*t=0; (2) if(d%2!=0)4.(1)for(i=2;i tj + 1 )8.(1)void fun(long s,long *t) (2)while(s0)9.(1)double r; (2) while(fabs(m-n)0.001)（注：n,m,）10.(1)bk=*p; (2) bk= ;k+;（注：单引号）11.(1)void fun (char *s, char *t) (2)t2*d = 0;12.(1)n=strlen( aa ) ; (2)ch=aai;13.(1)fun(int x,int y, int z)(2)return j;14.(1) void fun(int aM, int m)(2)ajk=(k+1)*(j+1);15.(1) c=tolower(c)(注：c小写); (2)c=c+5;16.(1) void fun(int *a)(2)aj=aj-1;17.(1) if (k%13 = 0) | (k%17 =0) (注：双等号) (2)（注：横线去掉）18.(1)for(i=1;i=0&k=i)20.(1)char *fun(char (*sq)M )(2)return sp;21.(1)switch(g)(2)case 1: return 1; case 2:return 1;22.(1)fun(int a,int m)(2)else if(mamid)23.(1) sum=0;(2)if(i+1)%5=0)24.(1)d=1;s=0;(2)d=d/10;25.(1) k=i;(2)c=k;26.(1) double fun(double a,double x0)(2)if(fabs(x1-x0)0.00001)27.(1)k+; (2)if(m=k)28.(1) for(i=0;stri;i+)(2)if(substrk+1=0)29.(1) float fun(int k)(2)return s;30.(1) q=p+i; (2)while(qp)31.
