結構問題：初始化將指針整數，未作鑄

Question

這裏是我的代碼：

#include <stdio.h> 
#include <string.h> 
#define Length 20 

    struct Capacitor 
    { 
     char Model[Length]; 
     int Capacitance; 
     float Voltage; 
     float Cost; 
    }; 

void displayCapacitorInfo(struct Capacitor List[]) 
{ 
    int i; 
    for (i = 0; i < 4; i++) 
    { 
     printf("Capacitor %s:\n\n", List[i].Model); 
     printf(" *Capacitance: %d uF\n", List[i].Capacitance); 
     printf(" *Voltage: %f V\n", List[i].Voltage); 
     printf(" *Cost: $%f\n", List[i].Cost); 
     printf("\n"); 
    } 
} 

int main() 
{ 
    float Cost, Voltage; 
    int Capacitance; 
    char Model[Length]; 

    struct Capacitor a; 
    struct Capacitor b; 
    struct Capacitor c; 
    struct Capacitor d; 

    strcpy(a.Model, "11-123U"); 
    a.Capacitance = 100; 
    a.Voltage = 25; 
    a.Cost = 6.00; 

    strcpy(b.Model, "65T91a"); 
    b.Capacitance = 22000; 
    b.Voltage = 20; 
    b.Cost = 25.00; 

    printf("Model number of 1st capacitor: %s\n", a.Model); 
    printf("Voltage of 2nd capacitor: %f V\n", b.Voltage); 

    printf("\n"); 

    printf("Model number of 3rd capacitor:"); 
    scanf("%s", &c.Model); 
    printf("\n"); 

    printf("Capacitance of 3rd capacitor:"); 
    scanf("%d", &c.Capacitance); 
    printf("\n"); 

    printf("Voltage of 3rd capacitor:"); 
    scanf("%f", &c.Voltage); 
    printf("\n"); 

    printf("Cost of 3rd capacitor:"); 
    scanf("%f", &c.Cost); 
    printf("\n\n"); 

    printf("Model number of 4th capacitor:"); 
    scanf("%s", &d.Model); 
    printf("\n"); 

    printf("Capacitance of 4th capacitor:"); 
    scanf("%d", &d.Capacitance); 
    printf("\n"); 

    printf("Voltage of 4th capacitor:"); 
    scanf("%f", &d.Voltage); 
    printf("\n"); 

    printf("Cost of 4th capacitor:"); 
    scanf("%f", &d.Cost); 
    printf("\n\n"); 

    struct Capacitor List[] = { {a.Model, a.Capacitance, a.Voltage, a.Cost}, {b.Model, b.Capacitance, b.Voltage, b.Cost}, {c.Model, c.Capacitance, c.Voltage, c.Cost}, {d.Model, d.Capacitance, d.Voltage, d.Cost} }; 

    displayCapacitorInfo(List); 

    return 0; 

} 

輸出：

我有我的數組列表的麻煩[]，特別是當我嘗試輸入電容器的型號時。結構體a，b，c和d的Model元素在輸入到數組List []中時會產生一個「初始化從指針沒有轉換的整數」警告。

我能做些什麼來解決這個問題？

感謝您的幫助。

首先，當使用scanf（「％s」）結構時，不應該使用&。檢查如何正確使用scanf與字符串。

然後用struct Capacitor List[]行了，我不知道你想要什麼用它做，但不是很容易只是爲了創造這些已創建結構指針數組是這樣的：

#include <stdio.h> 
#include <stdlib.h> 
#include <string.h> 
#define Length 20 

struct Capacitor 
{ 
    char Model[Length]; 
    int Capacitance; 
    float Voltage; 
    float Cost; 
}; 

void displayCapacitorInfo(struct Capacitor List[]) 
{ 
    int i; 
    for (i = 0; i < 4; i++) 
    { 
     printf("Capacitor %s:\n\n", List[i].Model); 
     printf(" *Capacitance: %d uF\n", List[i].Capacitance); 
     printf(" *Voltage: %f V\n", List[i].Voltage); 
     printf(" *Cost: $%f\n", List[i].Cost); 
     printf("\n"); 
    } 
} 

int main() 
{ 
    float Cost, Voltage; 
    int Capacitance; 
    char Model[Length]; 

    struct Capacitor a; 
    struct Capacitor b; 
    struct Capacitor c; 
    struct Capacitor d; 

    strcpy(a.Model, "11-123U"); 
    a.Capacitance = 100; 
    a.Voltage = 25; 
    a.Cost = 6.00; 

    strcpy(b.Model, "65T91a"); 
    b.Capacitance = 22000; 
    b.Voltage = 20; 
    b.Cost = 25.00; 

    printf("Model number of 1st capacitor: %s\n", a.Model); 
    printf("Voltage of 2nd capacitor: %f V\n", b.Voltage); 

    printf("\n"); 

    printf("Model number of 3rd capacitor:"); 
    scanf("%s", c.Model); 
    printf("\n"); 

    printf("Capacitance of 3rd capacitor:"); 
    scanf("%d", &c.Capacitance); 
    printf("\n"); 

    printf("Voltage of 3rd capacitor:"); 
    scanf("%f", &c.Voltage); 
    printf("\n"); 

    printf("Cost of 3rd capacitor:"); 
    scanf("%f", &c.Cost); 
    printf("\n\n"); 

    printf("Model number of 4th capacitor:"); 
    scanf("%s", d.Model); 
    printf("\n"); 

    printf("Capacitance of 4th capacitor:"); 
    scanf("%d", &d.Capacitance); 
    printf("\n"); 

    printf("Voltage of 4th capacitor:"); 
    scanf("%f", &d.Voltage); 
    printf("\n"); 

    printf("Cost of 4th capacitor:"); 
    scanf("%f", &d.Cost); 
    printf("\n\n"); 

    //struct Capacitor List[] = { {a->Model, a.Capacitance, a.Voltage, a.Cost}, {*b.Model, b.Capacitance, b.Voltage, b.Cost}, {*c.Model, c.Capacitance, c.Voltage, c.Cost}, {*d.Model, d.Capacitance, d.Voltage, d.Cost} }; 
    struct Capacitor *List; 
    List = malloc(4*sizeof(struct Capacitor*)); 
    List[0] = a; 
    List[1] = b; 
    List[2] = c; 
    List[3] = d; 
    displayCapacitorInfo(List); 

    return 0; 

} 

這是隻是一個簡單的例子，它應該比實際使用更具動態List[0] = a;等
