this is what is wrong?
Subject to code program, from a given search for a specified character string,

Input format:
The first line of the input is a character, to find the second line is a non-empty string ends with a carriage return (not more than 80 characters),

The output format:
If found, in a line according to the output format "index=subscript" the character in the string that corresponds to the largest subscript (subscript starting from 0); Otherwise output "Not Found",

Input the sample 1:
M
Programming
The output sample 1:
The index=7
Enter the sample 2:
A
1234
The output sample 2:
Not Found

 # include "stdio.h" 
# include "string. H" 
Int main () 
{
Char c, a, [100]. 
Int flag=100, I; 
The scanf (" % c \ n ", & amp; C); 
Gets (a);//the scanf (" % s ", & amp; A); Why to % s is wrong? Wrong a test point 
For (I=0; I & lt; Strlen (a); I++) 
If (c==a [I]) 
Flag=I; 
If (flag==100) 
Printf (" Not Found "); 
The else 
Printf (" index=% d ", flag); 


return 0; 
}

I mentioned repetition here is not to the original poster inside comments, specific problems on how to operate

CodePudding user response:

The scanf (" % c \ n ", & amp; C); Remove the here \ n,
Gets (a);//the scanf (" % s ", & amp; A); Why to % s is wrong? Wrong a test point in the scanf (" % s ", & amp; A) when, can't add & amp; The scanf (" % s ", a)

CodePudding user response:

refer to the second floor CHXCHXKKK response:

the scanf (" % c \ n ", & amp; C); Remove the here \ n,
Gets (a);//the scanf (" % s ", & amp; A); Why to % s is wrong? Wrong a test point in the scanf (" % s ", & amp; A) when, can't add & amp; The scanf (" % s ", a)

I tried as you said, only to have a test point is wrong

Reference:

 # include "stdio.h" 
# include "string. H" 
Int main () 
{
Char s [1], c, a, [81]. 
Int flag=1, I; 
The scanf (" % s ", s);//the scanf (" % c \ n ", & amp; C); 
C=s [0]; 
//gets (a); 
scanf("%s",a);//the scanf (" % s ", & amp; A); Why to % s is wrong? Wrong a test point 
For (I=0; I & lt; Strlen (a); I++) 
If (c==a [I]) 
Flag=I; 
If (flag==1) 
Printf (" Not Found "); 
The else 
Printf (" index=% d ", flag); 

return 0;

I tried your code, or you don't have a test point

reference room response: 1/f, the cloud

I mentioned no repetition to the building inside comments here, is the specific problems on how to operate the

Just knock on the compiler, is no problem, but I can't through test system has a test point

Title say non-empty string, didn't say that in the string does not contain Spaces,
