First experimental report

Summary of Knowledge points: 1-1 to 1-3 and 1-7: Write the text to precede the code with #include<stdio.h>; 1-4 to 1-6 and 1-8: Note that line breaks are in the quotation marks of printf ("") Nega \ n and every line of code in {} is preceded by a semicolon in English: Finally, the program should add return 0; Problems encountered: The number of times a success is too small, each experiment must be repeated several times, attention to the symbol of the Chinese and English problems. Experience: Programming should be careful, do not ask for fast, every letter to see well is not easy to make mistakes, to strive for high accuracy rate, for a successful, stable in seeking fast.
