PROGRAM: C

Answer 1

C PROGRAM =====>

#include <stdio.h>
#include <string.h>

int main()
{

int i, j, n,value;

printf("Enter the value of n \n");
scanf("%d", &n);
int age[n],tage[n],temp_age;
char name[n][15], tname[n][15], temp[8];

for (i = 0; i < n; i++)
{
printf("Enter %d names : ",i+1 );
scanf("%s", name[i]);

strcpy(tname[i], name[i]);
printf("Enter %d age : ",i+1 );
scanf("%d", &value);
age[i] = value;
tage[i] = value;
}

for (i = 0; i < n - 1 ; i++)
{
for (j = i + 1; j < n; j++)
{
if (strcmp(name[i], name[j]) > 0)
{
strcpy(temp, name[i]);
strcpy(name[i], name[j]);
strcpy(name[j], temp);

temp_age = age[i];
age[i] = age[j];
age[j] = temp_age;
}
}
}
printf("\nBefore Sort : \n");
printf("\n----------------------------------------\n");
printf(" Names age\n");
printf("------------------------------------------\n");

for (i = 0; i < n; i++)
{
printf("%s\t\t%d\n", tname[i], tage[i]);
}

printf("------------------------------------------\n\n");
printf("After Sort : \n");
printf("\n----------------------------------------\n");
printf("Sorted Names age\n");
printf("------------------------------------------\n");

for (i = 0; i < n; i++)
{
printf("%s\t\t%d\n", name[i], age[i]);
}
printf("------------------------------------------\n");

return 0;
}
