Implementing a shortest path algorithm in C

Hello,

I have a question. I have to implement a shortest path algorithm in n*n grid, moving from one coordinate to another coordinate.

But i have no clue how to start. Can anyone help?

Thanks a tonn in advance!

GLMAPGRID(3G)															     GLMAPGRID(3G)

NAME
glMapGrid1d, glMapGrid1f, glMapGrid2d, glMapGrid2f - define a one- or two-dimensional mesh C SPECIFICATION
void glMapGrid1d( GLint un, GLdouble u1, GLdouble u2 ) void glMapGrid1f( GLint un, GLfloat u1, GLfloat u2 ) void glMapGrid2d( GLint un, GLdouble u1, GLdouble u2, GLint vn, GLdouble v1, GLdouble v2 ) void glMapGrid2f( GLint un, GLfloat u1, GLfloat u2, GLint vn, GLfloat v1, GLfloat v2 ) PARAMETERS
un Specifies the number of partitions in the grid range interval [u1, u2]. Must be positive. u1, u2 Specify the mappings for integer grid domain values i=0 and i=un. vn Specifies the number of partitions in the grid range interval [v1, v2] (glMapGrid2 only). v1, v2 Specify the mappings for integer grid domain values j=0 and j=vn (glMapGrid2 only). DESCRIPTION
glMapGrid and glEvalMesh are used together to efficiently generate and evaluate a series of evenly-spaced map domain values. glEvalMesh steps through the integer domain of a one- or two-dimensional grid, whose range is the domain of the evaluation maps specified by glMap1 and glMap2. glMapGrid1 and glMapGrid2 specify the linear grid mappings between the i (or i and j) integer grid coordinates, to the u (or u and v) floating-point evaluation map coordinates. See glMap1 and glMap2 for details of how u and v coordinates are evaluated. glMapGrid1 specifies a single linear mapping such that integer grid coordinate 0 maps exactly to u1, and integer grid coordinate un maps exactly to u2. All other integer grid coordinates i are mapped so that u=i(u2-u1)/un+u1 glMapGrid2 specifies two such linear mappings. One maps integer grid coordinate i=0 exactly to u1, and integer grid coordinate i=un exactly to u2. The other maps integer grid coordinate j=0 exactly to v1, and integer grid coordinate j=vn exactly to v2. Other integer grid coordinates i and j are mapped such that u=i(u2-u1)/un+u1 v=j(v2-v1)/vn+v1 The mappings specified by glMapGrid are used identically by glEvalMesh and glEvalPoint. ERRORS
GL_INVALID_VALUE is generated if either un or vn is not positive. GL_INVALID_OPERATION is generated if glMapGrid is executed between the execution of glBegin and the corresponding execution of glEnd. ASSOCIATED GETS
