Help formatting text in c

What is a more stable version of \t that will let me indent lines of code without going all over the place. I need everything line up evenly.

Are you lining up your source code or the output from your program?

Most IDEs and editors have a "tabs as spaces" feature. You can specify the tab width as well, so your indentation might be 2, 4 or 8 spaces.

If you're talking about output in your code (e.g. from printf statements), then you need to use the width modifier. Generally, it's an integer between the % and the letter that specifies the type, like %6d or %10f or %-20s. You can use the - for left justification instead of the default right.

I did what you said anduril but the text is not alligning properly in my case 2 statement.(leaguestandings function)

Code:


#include <stdio.h>    
#include <stdlib.h>
 #include <string.h>
typedef struct {
char name[20];
        int wins;
        int loses;
        double pct;
        
        }TEAM;
        
void gameResult(TEAM* home, TEAM* away, int homeScore, int awayScore);
void calculatePCT(TEAM* team);
void leagueStandings(TEAM teams[]);
int getIndex(TEAM teams[], char* teamName);


int main()
{
      //declare variables
      TEAM teams[6];
  
  
   int input=0;
   int homeScore, awayScore, homeIndex, awayIndex;
   char home[20];
   char away[20];
   int i;
   for (i=0;i<6;i++){
       memset(teams[i].name,'\0',20);
   }
   memset(home,'\0',20);
   memset(away,'\0',20);
   sprintf(teams[0].name,"Houston");
   teams[0].wins=0;
   teams[0].loses=0;
  sprintf(teams[1].name,"Milwaukee");
   teams[1].wins=0;
   teams[1].loses=0;
   sprintf(teams[2].name,"StLouis");
   teams[2].wins=0;
   teams[2].loses=0;
  sprintf( teams[3].name,"Cincinatti");
   teams[3].wins=0;
   teams[3].loses=0;
  sprintf( teams[4].name,"Pittsburgh");
   teams[4].wins=0;
   teams[4].loses=0;

   teams[5].wins=0;
   teams[5].loses=0;
  
    
                           


while(input != 3){
    printf("Sports League Menu\n");
printf("1) Enter the result of the game\n");
   printf("2) Display the league standings\n");
   printf ("3) Quit the program\n");
   scanf ("%d", &input);
   switch(input){
   


  case 1:

      printf("Enter the home team's name:\n");
       printf("(Houston, Milwaukee, StLouis, Cincinnati, Pittsburgh, or Chicago\n\n");
      scanf ("%20s", &home);
      printf("Enter the away team's name:\n");
      scanf ("%20s", &away);
      printf("Enter the home score:\n");
      scanf ("%i", &homeScore);
      printf("Enter the away score:");
      scanf ("%i", &awayScore);
      homeIndex = getIndex(teams, home);
      awayIndex = getIndex(teams, away);
      
      if (homeIndex != -1 && awayIndex != -1)
         gameResult(&teams[homeIndex], &teams[awayIndex],homeScore, awayScore);
      else printf("invalid");
      break;

Code:

]$ gcc -g -Wall -o foo foo.c
foo.c: In function ‘main’:
foo.c:72:17: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘char (*)[20]’ [-Wformat]
foo.c:74:17: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘char (*)[20]’ [-Wformat]

Take the & off of the variable in the scanf calls on line 72 and 74. The name of the array serves as a pointer to the first element, so you don't need the &.

For the formatting, you need to put the 20 between the % and the s, or the % and the i, depending on how exactly you want the format. Also, look into using the - character for left justifying: "%-20s" will make the team name left justified and take up 20 spaces.
