unsigned int is a 32 bit type and size_t is a 64 bit type. If we pass a X64 int (4 bytes) as size_t (8 bytes) to a function which requires a 64bit size_t, we will receive above warning. You should be aware of where your code takes an int value and...
How could you be sure of that size_t is typedef for unsigned int. I run simple tester on visual studio 9 on 32 bit machine platform: unsigned int i =5; size_t j =6; i=j; Compiler gave me this warning warning C4267: '=' : conversion from 'size_t' to 'unsigned int', possible...
ESP32 I2S: int i2s_write_sample_nb(uint8_t sample){ return i2s_write((i2s_port_t)i2s_num, (const char *)&sample, sizeof(uint8_t), 100); } got error: invalid conversion from 'int' to 'size_t*' {aka 'unsigned int*'} [-fpermissive] how to fix?
上面调用了malloc函数，malloc函数的返回值是一个 void* ，而你直接赋值给student* 类型的变量p了，malloc前面加个强制转换就行，例如：student *p = (student *)malloc(sizeof(student));
