i m doing like this #define MAXROWS 100 float *arr[MAXROWS]; //read no of rows & cols from user for(i=0=i<rows;i++) arr = (float *)malloc(col * sizeof(float)); Here I can have rows at the max MAXROWS. Is it possible to have dynamic allocation of memory without knowing/declaring the maximum no of...

plz help me out ......my program is just above it......

Why am i getting wrong answer??? #include<stdio.h> #include<stdlib.h> int which_time_group( int a ); float func(char ch,int *u1,int *u2,int *u3,float R[][3],int lt[],int ut[],int a,int b,int c,int d); main() {int a,b,c,d,ph1,ph2,lt[3],ut[3]; int u1,u2,u3,i=0; float amnt; char ch; float R[5][3]; R[1]...

i have tried what adrian has said....but still error.....
my p is 4357186184021382204544

but my prog output is 4357186184021382004736

the difference is in the last few digits......
i have noticed that i had forgotten & in scanf earlier but this time i did what adrian had told me..

#include<stdio.h> #include<stdlib.h> void func(int N); main() {int N; do{ scanf("%d",&N); if(N == 0) exit(1); if(N==13) { printf("1\n"); continue; } /* printf("N = %d\n",N); */ func(N); }while(N != 0); } void func(int N) {int m; int check(int m,int N); for(m=1;m<=N...

i m stiil getting error my p is 4357186184021382204544 when double p; scanf("%Lf",p); printf("%0.0f",p); ANS is 0 when double p; scanf("%Lf",p); printf("%0.0Lf",p); ANS is 2805856302995564817576172202758523647276361706284109276003647136597093680332625552860574...

Even if what tiwari ji has told is true i don't see where my prog contradicts his argument....... Can any one give me a sample input where my prog fails to run..... i have alr...

The problem is still there whether i use %lf or %Lf

I m unable to read the long sample input.

But my problem is reading p when it is big. For the sample input I m failing to read the input.....[/code]
