Subject requirement is that the Insert function will Insert another string a string in the specified location, Insert part use {} name, but I was in my program '} ', but still output the garbled words, changed the ASC code also not line,

New people for help!!!!!!
Here is my code, if there is a problem where hope bosses can point to,

 # include & lt; Iostream> 
using namespace std; 

Int the Insert (char * dest, char * SRC, int pos); 

Char * S1, S2. 

Int main (int arg c, char * argv []) 
{
Char [80] s1 and s2 [80]. 
Int n, len; 

S1=S1; 
S2=S2; 

Cout & lt; <"Dest:"; 
Cin & gt;> S1. 
Cout & lt; <"SRC"; 
Cin & gt;> S2. 
Cout & lt; <"Pos:"; 
Cin & gt;> n; 

Len=Insert (S1, S2, n); Write://in the complete program calls the Insert function, 


Cout & lt; <"The output:" & lt; return 0; 
} 

Int the Insert (char * dest, char * SRC, int pos) 
{
int i, j; 
Char \ [80]. 

\ [0]='} '; 
For (I=pos, j=1; i <=strlen (dest); I++ j++) 
[j]=temp dest [I]; 
Dest (pos)=123; 
For (I=0, j=pos + 1; i <=strlen (SRC) - 1; I++ j++) 
Dest [j]=SRC [I]; 
Dest [j + 1)='\ 0'; 

Strcat (dest, temp); 

S1=dest; 

Return strlen (dest); 
} 

CodePudding user response:

Dest [j + 1)='\ 0'; To dest [j]='\ 0';//note for circulation after the location of j j, so dest [j]='\ 0'; Is correct, dest [m + 1] can cause dest [j] is a garbage characters, so will the code

Thank you very much. Bosses, didn't see such a simple question, it seems more to learn,
