c program for string concatenation?

Question

C program coding

Answer 1

Try using strcat() function (Be sure to include string.h). The syntax of this function is :

newstr = strcat(str1, str2 );

This means the function accepts two string "str1" and "str2" as arguments and concatenates them. The concatenated string is assigned to the variable "newstr".

Answer 2

Careful with the first parameter. There must be enough space allocated in that memory space because the second string will be appended. See the documentation link.

Are you asking for a function or a program? If a program, then I think we don't understand the question.

Answer 3

String a = strcat(str1, str2 );

Answer 4

this program concats 2 strings a,b using a user-defined function conc().
a and b are passed to the function and accepted in the variables x and y . the concated word is stored in z.
void conc(char x,char y)
{
int l1=strlen(x);
int l2=strlen(y);
l3=l1+l2;
char z[l3];
for(int i=0;i {
z[i]=x[i];
z[i+l1]=y[i];
}
cout.write(z);
}
hope this helps.

Answer 5

If you need ready function, use strcat().
Note that for strcat(s1, s2) s1 must have enough room to contain resulting string.
If you need your own function, it will be as:
s1 = realloc( s1, strlen(s1)+strlen(s2)+1);
strcpy( s1+strlen(s1), s2 );
That's all.

Answer 6

already defined fn in string library.
strcat()

Answer 7

There is already a function, strcat(), which does this for you.

Answer 8

str1="string1"
str2="string2"
str3 = str1 + str2;
this is simple. note its just a partial coding.
