c - Scanf将一个变量分配给C中的两个指针

Question

我想将用户的一个输入分配给两个不同的指针(我想将其读取为 float 和字符)。任何人都知道如何执行此操作或从一种转换为另一种的简单方法吗？

Answer 1

char inputString[MAX_SIZE]; // Your input will be stored here as a string.
float inputFloat;           // Here's where you will have your input as float
float *inputFloatPointer;

inputFloatPointer = &inputFloat; // Do this if you want 2 pointers, as requested

fgets(inputString, MAX_SIZE, stdin); // Read from your input buffer

if ((sscanf(inputString, "%f", inputFloatPointer)) == 1) // Try to parse it as a float
    printf("You read a float.\n");  // If the parsing succeeds, you have your float
else
    printf("This is no float.\n");  // Else the user typed something that's not a float.
