Question

HI I have following three strings,

char* string1, string2, string3;
printf("First string = %s", string1);
printf("Second string = %s", string2);
printf("Third string = %s", string3);

Output of above code is,

First string = My Content is : %s, My value is : %d
Second string = Open source OS
Thirf string = 100

Now i need to merge the string2 and string3 content at the place of %s & %d simultaneousaly, so that i should get following string,

My Content is :  Open source OS
My value is :  100

can any one suggest me how to add the above two strings to another string.
Thanks in advance.

Use sprintf along with printf as:

char format[1024]; 
sprintf(format, "First string = %s", string1); //this makes the format string
printf(format, value1, value2); //this prints output with the formatted string
