C中的数组数据类型

数组数据类型在C语言中的应用

c
int numbers[5];

c
int numbers[5] = {1, 2, 3, 4, 5};

c
int firstNumber = numbers[0];

c
numbers[2] = 10;

c
for (int i = 0; i < 5; i++) {
    printf("%d ", numbers[i]);
}

c
int matrix[3][3] = {
    {1, 2, 3},
    {4, 5, 6},
    {7, 8, 9}
};

c
int element = matrix[1][2];

c
int calculateSum(int arr[], int size) {
    int sum = 0;
    for (int i = 0; i < size; i++) {
        sum += arr[i];
    }
    return sum;
}
int main() {
    int numbers[] = {1, 2, 3, 4, 5};
    int sum = calculateSum(numbers, 5);
    printf("Sum: %d", sum);
    return 0;
}
