使用C语言编写一个违约管理系统

当然可以！以下是一个简单的违约管理系统的C语言示例代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX_CONTRACTS 100

typedef struct {
    char name[50];
    int contractNumber;
    float penalty;
} Contract;

void addContract(Contract contracts[], int *numContracts) {
    Contract newContract;

    printf("Enter name: ");
    scanf("%s", newContract.name);

    printf("Enter contract number: ");
    scanf("%d", &newContract.contractNumber);

    printf("Enter penalty amount: ");
    scanf("%f", &newContract.penalty);

    contracts[*numContracts] = newContract;
    (*numContracts)++;

    printf("Contract added successfully!\n");
}

void displayContracts(Contract contracts[], int numContracts) {
    if (numContracts == 0) {
        printf("No contracts found.\n");
        return;
    }

    printf("Contracts:\n");
    for (int i = 0; i < numContracts; i++) {
        printf("Name: %s\n", contracts[i].name);
        printf("Contract Number: %d\n", contracts[i].contractNumber);
        printf("Penalty Amount: %.2f\n\n", contracts[i].penalty);
    }
}

void searchContracts(Contract contracts[], int numContracts) {
    int contractNumber;

    printf("Enter contract number to search: ");
    scanf("%d", &contractNumber);

    for (int i = 0; i < numContracts; i++) {
        if (contracts[i].contractNumber == contractNumber) {
            printf("Name: %s\n", contracts[i].name);
            printf("Contract Number: %d\n", contracts[i].contractNumber);
            printf("Penalty Amount: %.2f\n\n", contracts[i].penalty);
            return;
        }
    }

    printf("Contract not found.\n");
}

int main() {
    Contract contracts[MAX_CONTRACTS];
    int numContracts = 0;
    int choice;

    do {
        printf("1. Add Contract\n");
        printf("2. Display Contracts\n");
        printf("3. Search Contracts\n");
        printf("4. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                addContract(contracts, &numContracts);
                break;
            case 2:
                displayContracts(contracts, numContracts);
                break;
            case 3:
                searchContracts(contracts, numContracts);
                break;
            case 4:
                printf("Exiting...\n");
                break;
            default:
                printf("Invalid choice. Try again.\n");
        }

        printf("\n");
    } while (choice != 4);

    return 0;
}

这是一个基本的违约管理系统，其中可以添加合同、显示合同列表和搜索合同。你可以根据自己的需求进行修改和扩展。希望对你有帮助！
