Created page with '<pre> unsigned int atoi(char* s, unsigned char len);  unsigned int atoi(char* s, unsigned char len){ unsigned int val=0; unsigned int flag=0; unsigned char i; for(i=0;i<len;i++) …'
New page
<pre>

unsigned int atoi(char* s, unsigned char len);



unsigned int atoi(char* s, unsigned char len){

unsigned int val=0;

unsigned int flag=0;

unsigned char i;

for(i=0;i<len;i++)

{

    if(s[i] >= '0' && s[i] <= '9'){val = val * 10 + s[i] -'0';}

    else if(s[0] == '-' && i==0){flag = 1;}

    else{break;}

}

if(flag == 1)

val = val * -1;

return val;

}

</pre>



example of the function being used:

<pre>

char c[10] = "123";

int i = atoi(c, 3);

printf("%d", i);
