将此伪代码转化成C语言代码

以下是将上述伪代码转换为C语言代码的例子：

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

#define MEMORY_SIZE 100 // You can replace with actual size or variable
#define SLEEP_MALLOC 5000 // Sleep for 5 seconds after allocation (in milliseconds)
#define SLEEP_FREE 2000  // Sleep for 2 seconds after deallocation (in milliseconds)

void memory_allocate(int size) {
    void* memory = malloc(size);
    if (!memory) {
        printf("Memory allocation failed.\n");
        exit(EXIT_FAILURE);
    }
    return memory;
}

void memory_deallocate(void* memory) {
    free(memory);
}

int main() {
    int i;
    for (i = 0; i <= 19; i++) { // Iterating from 0 to 19
        int current_size = i * MEMORY_SIZE;
        void* allocated_memory = memory_allocate(current_size);

        sleep(SLEEP_MALLOC); // Wait for 5 seconds
        memory_deallocate(allocated_memory); // Deallocate memory

        sleep(SLEEP_FREE); // Wait for 2 seconds
    }

    printf("Memory consumption test completed.\n");
    return 0;
}

在这个C语言代码中，我们首先包含必要的头文件，然后定义了内存分配和释放的函数，并在主函数中实现了循环过程，每次迭代会根据当前的`i`值计算需要的内存大小并进行分配和释放，同时插入相应的睡眠时间。
