Hi, I am studying about Pointers & String. I hardly understand them. I got many question but I try to ask directly.
This is a program that counts consonants
I want to know how strlen function worksCode:int strlen(char *s){ int n; for(n=0;*s!='\0';s++) if(isalpha(*s)) n++; return n; } void main(){ char str[]="I love C"; int len; len=strlen(str); printf("Lenght of %s is %d", str,len); }
Well since it's software, you can change it to do whatever you want.
Say
Also, main returns int, not void.Code:for(n=0;*s!='\0';s++) { if(isalpha(*s)) { n++; printf("Found char %c, n is now %d\n", *s, n ); } }
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
