Pls. help in C programming?

ok..so i wanted to make a program in C that is similar to the game FLAMES...for those who don't know the game: it's where you input 2 names and then the computer will then cancel the similar letter i name1 and in name2..(e.g. name1:marie yu name2:mark cruz.....2 m's will be cancelled, 2 a, 3 r's, ad 2 u's.....)then it will print the total nos. of canceled letters...


pls. guys help me..i need the entire C program, not just a detail of it..and pls. don't tell me to do my own homework or what because i try to do it myself but my knowledge in C programming is not that high..i try this many times but i can't do it.

Pls. help in C programming?

Reply:Did u ask ur professor?
Reply:just i ll give some logic u try it out..


let the strings be name1[ ] and name2[ ]





int count = 0;


for(int i=0; i%26lt;length of name1;i++)


{


fot(int j;j%26lt;length of name2;j++)


{


if(name1[i] == name2[j])


{


count++;


break;


}


}


}





i think you can do easily using this..


all the best
