simple struct

Description:

Write a C program to add two fractions and display the result fraction. Your program will prompt the user to input fraction 1 and fraction 2. The numerator and denominator of each fraction are input separately by space.  See the example output below:

Enter fraction 1(numerator denominator): 1 2  
Enter fraction 2(numerator denominator): 2 5  
Result: 9/10

10.    printf("

注意

函数的名字不能够直接进入赋值，必须要定义一个和函数一样的类型，返回函数值才能够，函数名称是用来调用的，不能够直接操作！
