Although C does not have a generic catch-all variable type, strings or arrays of characters can be used ( or misused ) to simulate the effect. Strings are often used to process arbitrarily large or small numbers which can't be represented by the C Standard Library. Strings are again used for this task to accept whatever the user enters. Each entry is treated as a string and is scanned. If any one of them contains a single 'non-number' character, then the whole set is treated as a set of strings.

int i,j,isString=0;
double val[MAX],temp;
for(i=0;i<MAX;i++){
printf("Enter %d%s value : ",i+1,(i==0)?"st":((i==1)?"nd":"rd"));
fgets(values[i],100,stdin);
for(j=0;values[i][j]!=00;j++){
if(((values[i][j]<'0' || values[i][j]>'9') && (values[i][j]!='.' ||values[i][j]!='-'||values[i][j]!='+'))
||((values[i][j]=='.' ||values[i][j]=='-'||values[i][j]=='+')&&(values[i][j+1]<'0' || values[i][j+1]>'9')))
isString = 1;
}
}
if(isString==0){
for(i=0;i<MAX;i++)
val[i] = atof(values[i]);
}
for(i=0;i<MAX-1;i++){
for(j=i+1;j<MAX;j++){
if(isString==0 && val[i]>val[j]){
temp = val[j];
val[j] = val[i];
val[i] = temp;
}
else if(values[i][0]>values[j][0]){
strcpy(tempStr,values[j]);
strcpy(values[j],values[i]);
strcpy(values[i],tempStr);
}
}
}
for(i=0;i<MAX;i++)
isString==1?printf("%c = %s",'X'+i,values[i]):printf("%c = %lf",'X'+i,val[i]);
return 0;
}
</lang>
The output shows three test cases, two as specified in the task, and one which mixes numbers and strings. The output is sorted considering all of them as strings in that case.
