String Programs
Malloc to initialize array, to check nth count of array!!
int *a;
printf("enter
the number of variables\n");
scanf("%d",&o);
printf("Variable
is %d\n",o);
a=(int*)malloc(o*sizeof(int));
printf("Enter
Elements of First List \n");
for (i = 0; i < o; i++) {
scanf("%d", a + i);
}
int
s=sizeof(a)/sizeof(int);
printf("\n%d\t%u\n",s,&s);
for(m=0;m<=3;m++)
printf("%d\n",a[m]);
Program for sizeof data types
#include
<stdio.h>
int main()
{
printf("Size of data type for
Char-%d!\n",sizeof(char));
printf("Size of data type for Short-%d!\n",sizeof(short));
printf("Size of data type for
Int-%d!\n",sizeof(int));
printf("Size of data type for
Long-%d!\n",sizeof(long));
printf("Size of data type for
Double-%d!\n",sizeof(double));
return 0;
}
Integer reverse program
#include<stdio.h>
#include<stdlib.h>
int main()
{
int i,cnt=0,o,count=0,l=0,cnt1=0,j=0,k=0,m;
int *a;
char b[5];
printf("enter the number of variables\n");
scanf("%d",&o);
printf("Variable is %d\n",o);
a=(int*)malloc(o*sizeof(int));
printf("Enter Elements of First List \n");
for (i = 0;
i < o; i++) {
scanf("%d", a + i);
}
printf("Reversed String is\n");
while(o!=0)
{
printf("%d\n",a[o-1]);
o--;
}
}
Pointer Initialization
#include <stdio.h>
int main()
{
int a=9;
int *p;
*p=0x012;
printf("%d\n%u\n%u\n",*p,p,&p);
*p=a;
printf("\n%d,%u\n",*p,&p);
return 0;
}
