An array of strings, please use the scanf writing prompt access conflict what reason be?-CodePudding

The code is as follows:

 
#include 
Int main () {
Char STR [6]. 

Scanf_s (" % s ", STR); 
Int CNT=0; 
For (CNT=0; CNT & lt; 5; Cnt++) {
If (STR (CNT) & gt;='A' & amp; & STR (CNT) & lt;='B') {
STR (CNT) -='32'; 
} 
Printf (" % s ", STR (CNT)); 
} 

return 0; 
}

Run to scanf_s that row times wrong is as follows:

 
0 x7ab1e63c (ucrtbased. DLL) (located in Project1. Exe) caused by abnormal: 0 xc0000005: when writing position 0 x00b00000 access conflict,

Which ensures that the input is 5 characters, such as: appLe,

Thank you very much!

CodePudding user response:

reference

printf (" % s ", STR (CNT));

this output because of changed to:

 printf (" % c ", STR (CNT));

CodePudding user response:

 scanf_s (" % s ", STR, 6);

Scanf_s and the difference between the scanf suggested that the building Lord search, then learn it
