用c语言和c++程序分别实现用户输入一个字符串和一个字符。然后，程序遍历整个字符串，统计指定字符出现的次数，并在找到指定字符时将其删除后输出新的字符串

C语言实现：

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

int main() {
    char str[100], ch;
    int len, i, count = 0;

    printf("Enter a string: ");
    gets(str);

    printf("Enter a character: ");
    scanf("%c", &ch);

    len = strlen(str);

    for (i = 0; i < len; i++) {
        if (str[i] == ch) {
            count++;
            continue;
        }
        printf("%c", str[i]);
    }

    if (count == 0) {
        printf("\nThe character '%c' is not found in the string.\n", ch);
    } else {
        printf("\n'%c' is found %d times in the string and removed.\n", ch, count);
    }

    return 0;
}

C++实现：

#include <iostream>
#include <cstring>

using namespace std;

int main() {
    string str;
    char ch;
    int len, i, count = 0;

    cout << "Enter a string: ";
    getline(cin, str);

    cout << "Enter a character: ";
    cin >> ch;

    len = str.length();

    for (i = 0; i < len; i++) {
        if (str[i] == ch) {
            count++;
            continue;
        }
        cout << str[i];
    }

    if (count == 0) {
        cout << "\nThe character '" << ch << "' is not found in the string." << endl;
    } else {
        cout << "\n'" << ch << "' is found " << count << " times in the string and removed." << endl;
    }

    return 0;
}
