I can't understand the sizeof in C

It gives you the sizeof the datatype of the variable not the value of the variable int x = 100; sizeof(x) == 4 x value is 100 but type of x is int and size of int is 4 bytes on 64 bit machine sizeof char is 1 byte float 4 byte double 8 byte pointer 8 byte on 64 bit 4 byte on 32 bit sizeof types is dependent on platform

While this example was written for C++ the logic still holds true for C... https://code.sololearn.com/cBss8k5523i1/#cpp

Thanks for help guys❤
