Program is for the purpose of the user input sentences upside down output, sen an array used to stor-CodePudding

#include
Int main () {
int i=0;
Char sentence [I];
Int j=0; Printf (" input a English sentence: ");

For ((what [I]=getchar ())='? '& & What [I]='! '& & What [I]!='. '; I++) {
;
}
Char sen_last=what [I];
Printf (" reverse the order of the sentence is: ");
int k=0;
int m;
Char sen [k].
For (j=I - 1; J>=0; J -, k++) {
Sen [k]=what [j];
If (sen [k]=='| | sen [k]==', ') {
For (m=k; M>=0; M -) {
Putchar (sen [m]);
}
k=0;
}
}
printf("\n");
Printf (" % d % d \ n ", j, k);
return 0;
}

Program is 14 questions out of the book

reference 1st floor weixin_40290083 response:

for (; (what [I]=getchar ())!='? '& amp; & What [I]!='! '& & What [I]!='. '; I++) {
;
}

What's the problem??

CodePudding user response:

Question 1
Don't use variable defined array length
The char sentence [I] to char sentence [256]

Question 2
For loop conditions do not use=, but==,
=='? '& amp; &=='! '& amp; &=='. '

Question3:
You are upside down character to be a whole sentence or words upside down? Now you sen [k]=sentance [j] it is character,

CodePudding user response:

refer to the second floor of Laplace's demon reply:

Quote: refer to 1st floor weixin_40290083 response:
for (; (what [I]=getchar ())!='? '& amp; & What [I]!='! '& & What [I]!='. '; I++) {
;
}

What's the problem??

Comparing this code and your code, be careful! Careful!!!!! Be patient!!!!!!

CodePudding user response:

What [I] is not a variable-length array declaration? The equal sign is actually!=but because I was using a mobile phone directly on the copy and paste, so lead to incomplete code
