How to solve this? Also, how about c1=% c into a single character?
CodePudding user response:
The compiled output results are as follows:
c1=a, c2=b Firstly, c1 and c2 is character type and assignment for 97 and 98 respectively
Printf (" c1=% c, c2=% c \ n ", c1, c2);//
this line mean the c1 and c2 with output printf () function output character of the way, although the original poster is not for c1 and c2 assignment is what character, but the assignment Numbers 97 and 98, and this involves a call ASCII, certain characters in the ASCII and Numbers are one to one correspondence, corresponding characters and 97 a, 98 b corresponding characters, so the printf output character and character b, I know that the original poster wants to warren, as to why such corresponding? This is a good agreement, why have this thing called ASCII, you can go to baidu encyclopedia, I also just learn C language soon, can't answer too much, Printf (" c1=% d, c2=% d \ n ", c1, c2);//
this line means the c1 and c2 using the printf function in the form of decimal output, the output is 97 and 98, What they don't understand, please continue to cross-examine,

Why don't you try it yourself? Programming or want to practice more
