代码作用是首先得到5行数字字符串
然后得到一个想要查找的重复数字型子字符串的长度和数字,比如长度3,数字0,就是查找'000'
然后判断第几行有子字符串,打印出来
我现在的问题是……不管有没有,返回结果都是有
还有最后一行的%s没有办法把数组字符串打印出来,我怀疑那个我整合的子字符串有问题,但是不太懂,求指点
int main(){
char r1[5],r2[5],r3[5],r4[5],r5[5];
int num=0,sn[10];
char tf[10];
int n,s;
gets(r1);
gets(r2);
gets(r3);
gets(r4);
gets(r5);
printf("Length of the sequence =");
scanf("%d",&n);
printf("Value of the sequence =");
scanf("%d",&s);
for (int i=0; i<n; i++) {
tf[i]=s;
}
for (int i=0; i<n; i++) {
printf("%d\n",tf[i]);
}
if(strstr(r1,tf)){
num++;
sn[num-1]=1;
}
if(strstr(r2,tf)){
num++;
sn[num-1]=2;
}
if(strstr(r3,tf)){
num++;
sn[num-1]=3;
}
if(strstr(r4,tf)){
num++;
sn[num-1]=4;
}
if(strstr(r5,tf)){
num++;
sn[num-1]=5;
}
printf("%d\n",num);
for (int i=0; i<num; i++) {
printf("在第%d行发现了%s\n",sn[i],tf);
}
}
The assic code value of 0 should be NUL.
It should be tf[i] = (char) (s + 48);
If it does not exist, a Null pointer is returned
