我正在嘗試做代碼來獲取學生姓名和ID,然後用穩定格式打印它。例如:(輸入名字和姓氏:「Alp David Oflas」輸入ID:「20110702037」,輸出結果應該像「OFLAS,Alp David,2011年以第37名學生的身份加入工程部門。」)所以我試圖用這個代碼,除ID部分,但在repl.it我gettin「退出非零狀態」錯誤,當我在Ubuntu上嘗試我gettin「分段錯誤(核心轉儲)」。所以直到4小時才能解決這個問題。你能幫我哪一部分代碼導致這個錯誤嗎?字符串上的分段錯誤C
注:我不能使用任何其他功能。我必須循環做比較。
#include <stdio.h>
void output(char name[100],char ID[100]){
char surname[100];
//Calculating name string's length//
int nameL;
for(nameL=0;name[nameL]!="\0";nameL++);
int i=nameL;
int j=0;
int flag;
flag = "FALSE";
//Geting surname from value with decreasing i. It could be something like "Alp David Oflas" so we need just surname//
while (flag="FALSE"){
if (name[i] == " "){
flag="TRUE";
}
else{
surname[j] = name[i];
i--;
j++;
flag = "FALSE";
}
}
surname[j]="\0";
//Previous surname just be like "salfO" so need to convert it//
char newsurname[100];
int surnameL;
for(surnameL=0;surname[surnameL] !="\0";surnameL++);
int k=0;
while (surname[k] != "\0"){
newsurname[k]=surname[surnameL];
k++;
surnameL--;
}
newsurname[k] = "\0";
//Just capitalizing surname for dependant output//
int x=0;
while (newsurname[x] !="\0"){
if (newsurname[x] >= "a" && newsurname[x] <= "z"){
newsurname[x] = (newsurname[x] -32);
}
x++;
}
printf("%s",newsurname);
}
//Geting values from keyboard//
int main(){
char name[100];
char ID[100];
printf("Enter name and surname:\n");
gets (name);
printf("Enter ID:\n");
gets (ID);
output(name,ID);
return 0;
}
調查每個警告。 –
@DavidSchwartz喜歡(不要用「gets」) –
'int flag; flag =「FALSE」;而(flag =「FALSE」)'看起來不正確。 – Pang
