Thread: how to split a string into different parts?

Sample input string

The program must separte each input line into 4 parts. first name, age, last name, and age+7, the following code is a sample of with only 2 component, I don't know how to do it with 4 components. Could someone edit the code for me please.

Code:

void main(int argc, char *argv[])
{
	struct person list[];
	int i,n;
	char *ch, *ch1;
	char buf[256];
	FILE *file1;
	i=0;
	fgets(buf,250,file1);    

	while(!feof(file1))
	{
	ch=strchr(buf,'\n');
	if (ch!=NULL) *ch='\0';
	else break;
	ch = strchr(buf, ' ');
	if(ch!=NULL) 
                 { 
                 *ch='\0'; 
                 ch1=++ch;  //age
             
                  }
	else break;
	strcpy(list[i].lastname,buf);
                list[i].age=atoi(ch1);
	i++;		
	fgets(buf,256,file1);
	}

	n=i;
	for(i=0;i<n;i++)
              printf("%s is %d years, first name is %s\n", list[i].lastname, list[i].age); 
    }

strtok or strsep will do this though strsep doesn't conform to C99 standard. A space ' ' delimiter would be used.

you can use sscanf to parse the string into tokens

could you show me how you could do in the code above please.
