I want to read numbers(integer type) separated by spaces using scanf()
function.
I have read the following:
It doesn't help me much.
How can I read numbers with space as delimiter. For e.g. I have following numbers as input 2 5 7 4 3 8 18
now I want to store these in different variables.
Please help.
scanf
uses any whitespace as a delimiter, so if you just say scanf("%d", &var)
it will skip any whitespace and then read an integer (digits up to the next non-digit) and nothing more.
Note that whitespace is any whitespace -- spaces, tabs, newlines, or carriage returns. Any of those are whitespace and any one or more of them will serve to delimit successive integers.
int main()
{
char string[200];
int g,a,i,G[20],A[20],met;
gets(string);
g=convert_input(G,string);
for(i=0;i<=g;i++)
printf("\n%d>>%d",i,G[i]);
return 0;
}
int convert_input(int K[],char string[200])
{
int j=0,i=0,temp=0;
while(string[i]!='\0')
{
temp=0;
while(string[i]!=' ' && string[i]!='\0')
temp=temp*10 + (string[i++]-'0') ;
if(string[i]==' ')
i++;
K[j++]=temp;
}
return j-1;
}
It should be as simple as using a list of receiving variables:
scanf("%i %i %i", &var1, &var2, &var3);
