我目前的代碼有問題，特別是 If-else 部分。如果我的年級為 1，則滿足 if-else，但如果我輸入的年級為 2、3 或 4，則滿足這些的 if-else 但是，它始終顯示 yrep1 的 if-else （它總是列印“年級代表：卡梅爾夫人”）除非年級為 1。
int year, yrep1, yrep2, yrep3, yrep4;
char gov1[] = "Juan Dela Cruz";
...
char fiy1[] = "Lady Carmel";
printf("\nEnter Year Level: ");
scanf("%d", &year);
if(year==1){
printf("\n\n\t\t\t CANDIDATES FOR FIRST YEAR LEVEL REPRESENTATIVE ");
printf("\n\n1. Lady Carmel");
printf("\n\n2. Zia Alonzo");
printf("\n\nEnter your vote(Ex. 1): ");
scanf("%d", &yrep1);
printf("\nVote has been recorded!");\
}else if (year==2){
printf("\n\n\t\t\t CANDIDATES FOR SECOND YEAR LEVEL REPRESENTATIVE ");
printf("\n\n1. Lita Cordova");
printf("\n\n2. Mariel Geronimo");
printf("\n\nEnter your vote(Ex. 1): ");
scanf("%d", &yrep2);
printf("\nVote has been recorded!");
}else if (year==3){
printf("\n\n\t\t\t CANDIDATES FOR THIRD YEAR LEVEL REPRESENTATIVE ");
printf("\n\n1. Carmel De Leon");
printf("\n\n2. Helen Sy");
printf("\n\nEnter your vote(Ex. 1): ");
scanf("%d", &yrep3);
printf("\nVote has been recorded!");
}else if (year==4){
printf("\n\n\t\t\t CANDIDATES FOR FOURTH YEAR LEVEL REPRESENTATIVE ");
printf("\n\n1. Stephen Cortes");
printf("\n\n2. Olivia Yu");
printf("\n\nEnter your vote(Ex. 1): ");
scanf("%d", &yrep4);
printf("\nVote has been recorded!");
}
if(yrep1==1){
printf("\n\n\tYear-level Representative: %s", fiy1);
}else if(yrep1==2){
printf("\n\n\tYear-level Representative: %s", fiy2);
}
if(yrep2==1){
printf("\n\n\tYear-level Representative: %s", sy1);
}else if(yrep2==2){
printf("\n\n\tYear-level Representative: %s", sy2);
}
if(yrep3==1){
printf("\n\n\tYear-level Representative: %s", ty1);
}else if(yrep3==2){
printf("\n\n\tYear-level Representative: %s", ty2);
}
if(yrep4==1){
printf("\n\n\tYear-level Representative: %s", foy1);
}else if(yrep4==2){
printf("\n\n\tYear-level Representative: %s", foy2);
}
printf("\n\n\t\t\t\t\tBALOT RECEIPT");
printf("\n\n\tNAME: %s", name);
printf("\t\t\t\t\tDATE: %s", ctime(&t));
printf("\n\tYEAR LEVEL: %d", year);
printf("\n\n\tYEAR SECTION: %s", section);
printf("\n\n\t\t\tYOU'VE VOTED FOR THE FOLLOWING CANDIDATES:");
uj5u.com熱心網友回復：
問題是這些變數
int year, yrep1, yrep2, yrep3, yrep4;
未初始化并且具有不確定的值。
例如，您需要用零初始化它們。
int year, yrep1 = 0, yrep2 = 0, yrep3 = 0, yrep4 = 0;
另一種方法是將 if-else 陳述句包含在另一個 if 陳述句中，例如
if(year==1)
{
if(yrep1==1){
printf("\n\n\tYear-level Representative: %s", fiy1);
}else if(yrep1==2){
printf("\n\n\tYear-level Representative: %s", fiy2);
}
}
