How to compare strings - c?

Say I have a string named speed , and I want to check it against acceptable string values . How would I do this , I know how to compare integers but not strings .

How to compare strings - c?
I assume that you have two strings to compare. In C language, string are character array. So, Let the string to compare is speed, with a set of given strings. let you have defined that set of strings as an array of string , i.e., two dimensional array of charecter. With these assumptions, perform following steps:


char *spped;// or you can declare as char spped[SIZE];


char *Values[MAX];// MAX is maximum number of allowable string values.


int i;


for(i=0;i%26lt;MAX;i++)


{


if(strcmp(speed, Values[i]) == 0)


{printf("string is valid");}


}


you should include %26lt;string.h%26gt; to use strcmp().


If U like the answer, PLZ, do rate as best answer
Reply:use the strcmp() or strncmp() funcitons.





Or, you could write your own function to compare byte for byte.
